Some interesting log entries from BIND 4.9.3BETA24...:

356. fixed odd corner case bug in res_query().

202. name compression is now case-insensitive.

86. a long standing bug in the name hashing code that caused it to ``hash in''
    the case of the name's characters, was found and fixed.  (twice.) (Vixie)

84. the RFC1101 implementation of getnetby*() was using case-sensitive
    string compares.

My guess is that one or more of these may be what causes some older versions
of BIND to sometimes claim no matches...
