Duplicate RRs are suppressed, as per the standards.
RFC 2181, Section 5:
Each DNS Resource Record (RR) has a label, class, type, and data. It
is meaningless for two records to ever have label, class, type and
data all equal - servers should suppress such duplicates if
encountered
That being said, a DNS-based load-balancer can probably do what you're
looking for.
