Actually, a '0' would also be returned if you're outside the goup name length limts, I believe. Thus, the INGROUP() is actually working as expected. However the group names are way too long and should be shortened.
Just excluding Windows 9x clients is a workaround and shouldn't really be done. Fix the underlying problem, don't cure the symptoms. This way, you end up with a well-documented and correctly setup network.
