Missed plate on a time play

[Morningrise]

Long time lurker here.

R1 on 3rd base, R2 on 1st base, one out, bottom 7th inning, score tied. Batter hits a fly ball. R1 stays on third, but R2 takes off for second. The ball is caught by F9, who fires to first. R1 heads for home and crosses the plate just before F3 catches the throw and touches first base to retire R2. However, R1 missed touching the plate.

My question is: How do you announce the result of the time play without revealing to either team that R1 missed the plate? Is it acceptable to say "the run scores" or "the game's over" when a potential appeal exists that could cancel the run and continue the game? If not, what do you say if the defense's coach asks "so is the game over?"
