OK, so you're thinking:

FMPS_Rating (canonical user-defined rating)
FMPS_Rating_Critic_Ralph=Gleason
FMPS_Rating_Critic_Metacritic
<snip>

Sounds good to me.

Yes, this should be explicitly mentioned.

I can live with local conventions, but for ease of readability for
someone actually trying to modify their tags by hand -- plus ease of
parsing -- I'd prefer to keep the underscores. So FMPS_Rating on MP3 and
FMPS_RATING on Vorbis work?

Yes, I was planning on that for ASF (just haven't written that in yet).

That sounds good.
