In oher words, it was not worth having a look at the 'result' unless
FcTypeResultMismatch is raised in FcCompareValueList(). I could set
FcResultMatch at the end of FcFont{Sort,Match} and
FcFontSet{Sort,Match} if the return value is valid though.

For a workaround, you can do similar thing in fc-match.c where your
reference points to.

Anyway, thanks for catching this up.
