Perhaps the zone got updated between your queries. Have you (as one should in a proper experiment) repeated these queries to demonstrate that this is happening consistently? If it is happening consistently, then it's possible that you have *two* DNS servers listening on the server, one on the UDP socket, and another on the TCP socket, and they're loaded with different zones.
