As far as I know, all DNS queries for IPv6 addresses are still done
over the V4 stack. I saw IPv6 transport on the TODO list in 8.1.2.

Beyond that, it's a bit ugly, but not complicated. Just enter AAAA
records as you would A records.
www-6tap        IN      AAAA    3ffe:700:20:4:a00:2bff:fe91:d412

The reverse entries are still just PTR records, but they are REALLY
ugly. The one above would have a reverse of:
2.1.4.d.1.9.e.f.f.f.b.2.0.0.a.0.4.0.0.0.0.2.0.0.0.0.7.0.e.f.f.3.ip6.int. PTR www-6tap.es.net.

You only have to include the address to the zone cut, so it would be
more likely to look something like:
2.1.4.d.1.9.e.f.f.f.b.2.0.0.a.0.4 PTR www-6tap.es.net.
