Description

The previous random sort for weights in a dispatcher set distributed correctly only after a minimum of n=100 calls.
This PR fixes the sort algorithm to distribute calls based on those weights, even for n<100 calls.
The real benefit here is customers can see the weighted distribution occur sooner now, when testing.
