Thus spake Jack Carrozzo (jack () crepinc com) on Wed, Jan 26, 2011 at 01:38:48PM -0500:
As I understand it, when a client requests a particular domain of yours and gets
an A and an AAAA, the client will default to the AAAA (assuming it's on a v6
network) and attempt to communicate as such. Failing that, it will fall back
to the v4 A record.

This is true for now.  

See http://tools.ietf.org/html/draft-wing-v6ops-happy-eyeballs-ipv6
for a proposal on how this could change.
