scheme with multiple same-name durations, not all of which will be discarded

[ehunt]

Joining game #5090 on frankfurt-test2.

In this game I play a scheme at some point in turn 12. In the cleanup phase I have three archives in play:
one which I played this turn, which will stay in play
one which I played the previous turn, which will stay in play
one which I played two turns ago, which has given me its last card, and which I will discard.

I want to scheme an archive, but I can't tell which one to pick (they are all lumped together) and when I try to scheme, the archive doesn't go on top (I assume because the server thinks I'm picking the "wrong" one).
