According to the OP, N/S did have an agreement, but South had forgotten it.
Yes it was clear that N/S had an agreement and South had forgotten it.
I think we should assume that West, if given the correct explanation of 2NT (majors), would double 3
♦ (as he stated he would). It is clear that, absent that double, the 3
♠ bid by North makes use of UI (South's wrong explanation). Does the situation change significantly when West interposes a double? South's passed hand status does help a bit North's case for self-rescuing. As TD, I considered (too hastily, I see now) that over the double the 3
♠ bid would be the normal action by North, and ruled a weighted adjusted score based on 4/5
♦ contracts by E/W only; upon reading other posts and rethinking the issue, I believe that passing the double remains an LA. (I also admit that I didn't pursue the issue of what kind of hand with long diamonds South might have, not having preempted in 1st position).
IF we accept a 3
♠ bid over the double: does that bid make clear to everyone at the table that North has the majors? I think so. I also think that the normal move by East would then be to bid 4
♦ (at least; some might consider that 5 card support + KJ in partner's first suit + an outside ace would justify a stronger move, for someone who previously passed). I don't think either N or S would bid 4
♠ (which might prompt a very unsuccesful double), but E/W just might drift to 5
♦ on their own momentum.
What would have been the correct ruling (weighted scores allowed)? Some of EW 4
♦ made, 4
♦ -1, 5
♦ -1, 5
♦ -2, and/or NS 3
♦ doubled -6 or so?
