I think we discussed this ASA/NFHS difference about a month ago but I can't find the thread now.

And I have to leave for the ballpark!

Here is the text cut and pasted from the 2011 NFHS SB Case Book:

9.1.1 SITUATION N: R1 is on second base, R2 on first base with one out. B4 hits safely to the outfield. R1 scores, R2 misses second base and is standing on third base when B4 is thrown out at second base. A dead-ball appeal is properly made on R2 for missing second base. The umpire rules R2 out for the third out.
Does R1's run count?
RULING: No. Since R2 was forced to advance to second base, the appealed out at second base was a force out. No runs can score if the third out of an inning is the result of a force out. (8-6-7; 9-1-1 Exception b; 2-1)
