I just tested with my PowerDNS + mysql and it seems that PowerDNS does always return the answer rrset sorted, _but_ your recursive Nameserver will always randomize that response before it gets sent to the client hence your nslookup will be given a randomized response and thus present you with a different answer each time you do a lookup. So, there definitely is support for round-robin-sets in PowerDNS. There sure are some solutions that use PowerDNS and add/remove records to mysql on failover conditionals but i don't know of any that are publicly available.
