A simple way to solve this is with multiple routing tables.

Create multiple routing tables with:
route -T1 add default <gw1>
route -T2 add default <gw2>
route -T3 add default <gw3>

And start the 3 squid processes with route -T1 exec, route -T2 exec.
You can also use the the *_rtable variable in rc.d(8) to do that
automatically.

This requires that the 3 squids listen on different IPs or ports.
