RFC1034
If a CNAME RR is present at a node, no other data should be
present....

BIND 9 does random starting records with same ordering by
default, and I don't think there is an easy DNS based way within
BIND 9 to achieve the same effect.
Load balancing has been discussed extensively in the archive,
with lots of different ideas, although a lot depends what you
are trying to do. Dynamic DNS offers the option to remove
overworked or dead servers.
