We cannot predict the full enforcement date so I would probably if I were you avoid 2014 (as you note the full enforcement date would be acceptable as the language subtag name after all ratify this treaty).

A question for you:  is it acceptable to you to use abbreviations of the Portuguese terms for this treaty, "acordo -> acord" or "convencao -> conv" ? I suppose these end up being too opaque.)

Hmm.  Sometimes people have suggested doing this with country codes (when the regional boundary is the country).  Of course indicating that a language is pt-[xxxxxxxx]-PT or anything else does not mean it is Portuguese Portuguese as specified by the 1990 treaty.
Do you prefer to register a variant instead of using PT, etc?

I agree with Phillip here.
