As others have said, if a name has a CNAME record, it may have no others
[with a few DNSSEC exceptions].

DNS is not the right way to do round robin, anyway.  The user's caching
resolving name server will serve out the names how it wants, not how you
want [not necessarily, anyway].  Use a Squid proxy or an F5 BigIP or
something like that.
