This is not how you do it. DNS clients are expected to choose one record 
at random for establishing connections. So the order in which the server 
returns results has no impact. Unbound is right not to waste time 
changing the order.

The right way to do DNS-based load balancing (if there is one!) is to 
have the server return a subset of RR set. And Unbound doesn't have that 
feature (which some might call a bug, and for valid reasons!).
