That is an excellent suggestion, but I read the following
statements in DNS and Bind, Fourth Edition:
Round Robin Load Distribution (DNS and BIND, 4th Edition) (p5 of 9)
10.7.2. The rrset-order Substatement
There are certain times when you'd rather the name server didn't use
round robin. For example, maybe you'd like to designate one web server
as a backup to another. To do this, the name server should always
return the backup's address after the primary web server's address.
But you can't do that with round robin; it'll just rotate the order of
the addresses in successive responses.
BIND 8.2 and later name servers -- but not BIND 9 name servers, as of
9.1.0 -- allow you to turn off round robin for certain domain names
and types of records.

Unfortunately, that's us.
BIND 9.2.2rc1
Unless that feature got put back, we may be in a bit of a jam.
