I can confirm that my particular issue is fixed, but I believe that commit
07485a697552641609df73fd411de1ea964f1ef2 introduced a discrepancy, because
now the filter logs when score is '''greater than or equal''' to threshold
(see line 166), but (if sc_pass==1) it forwards the frame only if the
score is '''strictly greater''' than threshold (see line 173).
This behaviour is probably unexpected since it does not conform to
documentation.
I suggest correcting line 173 as well.
