I am assuming that by 'prior' you mean taken into account earlier in
the processing.  If you don't, please ignore my post.

I OpenType (I don't know about AAT) has a new type of look-up table
in the cmap table, format 14, which converts a combination of base code
point and variation selector to a glyph.  If one uses this - I haven't
experimented with using it - FVS is necessarily prior to MVS in the
order of substitutions.
