Playing beyond third out

But this drags on so long that after the third actual out is made, the umpires don't realize there are three outs. Two more batters come up to bat before the defense realizes, "hey wait... There are 3 outs."

What do you do?

Speaking ASA

That half of an inning is over when the third out is recorded. Any subsequent action is irrelevant. (Rule 1-Inning). No runs can score after the 3rd out of a half-inning (5.5.B).

Ignore everything which happened after the 3rd out was executed. The batter due up at the beginning of that teams next at bat would be the first extraneous batter in the previous inning.
