I think this is your problem. From what I understand BIND does not do this.
It will contact the last server that it received an update from and check
the serial, if it's greater then it will update, but it certainly won't
chase around each master server looking to see if one of them has a higher

I think you need to fix the way you have implemented the masters, BIND
doesn't support multi-master DNS which is what you are trying to implement.
If you need this functionality then Microsoft does (to a point, there still
is effectively a master but as it's distributed through LDAP it handles
multiple updates in the background using a timestamp of the update as the
decider) but then IMHO it's just not BIND.
