I never gave it a try on linux (on winxp it seems to work): 'metric' is for 
that purpose.
See 'route -n' and/or 'man route'.

The man page says:
       Metric The  'distance'  to  the target (usually counted in hops). It is
              not used by recent kernels, but may be needed  by  routing  dae-
              mons.

sorry, not a solutuion. more like a hint.
