Last Play of the Game Question

[starman]

I think I did a bad job of wording my orignal question. How about this....

Bases Loaded, bottom of the last inning, tie game. OBR rules. Batter hits a ground ball to 3B. Defense turns what appears to be a 5-4 double play. However, the batter and runner on third are very fast. The run scores and the batter tags first before the out is recorded at 2B.

My interp of 4.09b is that the game was over before the out at second. The runs scores and the game is over. If the same thing had happened in the first inning, no runs scores. Am I wrong?
