The answer is BIND does accept TCP queries by default (it's required to be RFC compliant), but a lot of times upstream firewalls/ACLs/etc block TCP, munge UDP packet size, etc... Just firing up BIND with basic configuration and checking netstat will show you TCP 53 listening. If it's not working as expected, you often have to start walking up (or down as it were) the stack and potentially working with other folks to fix the problem.
