BIND also keeps track of server response times, so it can reduce average latency by preferring servers that respond faster. I guess that this is what you are seeing. You might find that you can test lameness with fewer confounding factors if your lame server responds with an error (REFUSED or SERVFAIL) instead of dropping the query.
