How many score?

[bossman72]

Situation is R2, R3. 1 out. Batter hits a fly to F8. 2 outs. F8 tries to nail R3 at home, but the ball is thrown wild and both runners score. Defense then appeals that R3 left third too early. The umpire calls him out.

No runs score on this play, correct?

My reasoning would be that if you appeal for a missed base or a tag up play for the third out after the play has ended, then no following runners can score. Is this right? Would this also be true for that rare "4th out?"

Thanks
