Say the server has native IPv6 address 2001::1 and 6to4 IPv6 2002::X. Say the client has native IPv6 address 2003::1 and 6to4 IPv6 2002::Y. Longest prefix match will choose 6to4 over native IPv6. Not good.
Surely the longest prefix only wins over prefixes that cover the long prefix.
What you seem to be suggesting is that a client will somehow be able to deduce the prefix length for two bare v6 addresses received from the DNS, and will choose the one with the longest prefix first. That seems unlikely to be the case in general.
