Last time I tried to archive something, I hit the leftmost button, since a down-arrow on a folder kind of seems like an archive function. Then I hit the rightmost button, since it seemed like an action. Finally I hit the trash, because it was the only one left.

One interesting thing about this design is that if there were separate trash/archive icons, they would probably have confirmation popups, and so the number of taps is the same either way.
