Try the dig without @my-dns-server. That'll give you a better baseline
comparison to how ordinary commands like "ping6" resolve DNS from that box.
Also, if you have control of my-dns-server, turn on query logging (if
not already turned on) and see if you're actually getting AAAA queries
for ipv6.google.com from the client.
Alternatively, fire up a sniffer or network tracer of some kind.
