Option A: round-robin+sortlist
Option B: views

Appropriate caveats for each approach.

Note that if these are Windows clients on the same subnets as the 
www.example.com addresses, you could probably just get away with a plain 
old round-robin and rely on the built-in Windows "subnet 
prioritization", see
