Tomas,

Perhaps you want a summary of how the kernel makes a routing decision?

See my description of the route selection process:

  http://plorf.net/linux-ip/html/routing-selection.htm

I'm not sure you need policy routing though...  If network B is reachable 
from network A, and the router for network B is directly connected to 
network A but is not the default gateway, you'll have something sort of 
like this:

network-C via router-B
network-B via router-B
network-A dev ethX
default via default-gw

Is this your configuration?  If so, then you need no policy routing.
