Do you have randomize_recs enabled in your pdnsd config?

randomize_recs=(on|off);
If this option is turned on, pdnsd will randomly reorder the cached
records of one type when creating an answer. This supports round-robin
DNS schemes and increases fail safety for hosts with multiple IP
addresses, so this is usually a good idea.
On by default.
