I would suggest you to divide the problem in two parts:
1) Imagine that your two ISP connections never fail and only make a configuration where subnet A goes to ISP1 and subnet B goes to ISP2, this can be done by marking connections through firewall mangle or through routing rules, and a second routing table, if you search you will find existing threads about using the one or the other method.
2) then, only once the above is tested and works, add to the setup the failover method via netwatch
I have very little experience with both mangling and routing rules, from what I know mangling is the traditional way, so there are more related threads and examples whilst routing rules is relatively newer but is (IMHO) simpler and should also cause less CPU usage (though that shouldn't be an issue anyway in your simple setup).
