Rrset-order was introduced in 8.2 and dropped with 9.1, but it is not =
needed to do round-robin; it is used to turn round-robin off.

The default since 4.9 has been to round-robin (give out multiple records =
in cyclic order). All you have to do is add more records and it will =
round-robin by default. Note that BIND 9 rotates all records types, but =
earlier versions did not rotate PTR records.

All of this information is in DNS and BIND and available on-line.
