priority with A record?

[John Wobus]

All the previously-mentioned issues apply, but (obviously)
round robin could be made to offer a select server twice as
often by giving that server an additional address and
A record.  Something similar for nameservers could
be devised.

I had a vague recollection that one could simply
duplicate an A record in the zone file, but perhaps my
memory is playing tricks on me.
