Ground rule double question

[BiZmaRK]

Bottom of the ninth, score tied, bases loaded. Batter hits a ground rule double. How many runs score and what is the batter credited with?

Rule 10.06
(f) Subject to the provisions of Rule 10.06(g), when a batter ends a game with a safe hit that drives in as many runs as are necessary to put his team in the lead, the official scorer shall credit such batter with only as many bases on his hit as are advanced by the runner who scores the winning run, and then only if the batter runs out his hit for as many bases as are advanced by the runner who scores the winning run.

Rule 10.06(f) Comment: The official scorer shall apply this rule even when the batter is theoretically entitled to more bases because of being awarded an “automatic” extra-base hit under various provisions of Rules 6.09 and 7.05.

The official scorer shall credit the batter with a base touched in the natural course of play, even if the winning run has scored moments before on the same play. For example, the score is tied in the bottom of the ninth inning with a runner on second base and the batter hits a ball to the outfield that falls for a base hit. The runner scores after the batter has touched first base and continued on to second base but shortly before the batter-runner reaches second base. If the batter-runner reaches second base, the official scorer shall credit the batter with a two-base hit.

(g) When the batter ends a game with a home run hit out of the playing field, the batter and any runners on base are entitled to score.

I would think the winning run would score before a ground roll double is even called if the bases are loaded .... so the first run would end the game .... I mean if there is a homerun obviously all runs are counted. The only other way I could see it playing out is if the batter hits a shot and the runners are tagging and it one hops out .. I would think two runs would be credited but thats just me.

If the batter never touches first base, would this affect how many runs score?

If the batter never touches first base, would this affect how many runs score?

If there were two outs, and the defense appeals that the batter didn't touch first, inning is over, no runs count, game is tied, play on.

If there are less than two outs the game is over when the winning run scores.

Rule 4.11 The score of a regulation game is the total number of runs scored by each team at the moment the game ends.
(c) If the home team scores the winning run in its half of the ninth inning (or its half of an extra inning after a tie), the game ends immediately when the winning run is scored. EXCEPTION: If the last batter in a game hits a home run out of the playing field, the batter-runner and all runners on base are permitted to score, in accordance with the base-running rules, and the game ends when the batter-runner touches home plate.
APPROVED RULING: The batter hits a home run out of the playing field to win the game in the last half of the ninth or an extra inning, but is called out for passing a preceding runner. The game ends immediately when the winning run is scored, unless there are two out and the winning run has not yet reached home plate when the runner passes another, in which case the inning is over and only those runs that scored before the runner passes another shall count.
