From the route man page.  I think 'metric' is the same as the count in the command:

count         

An integer that indicates whether the gateway is a remote host or the local host.  If the route leads to a destination through a remote gateway, count should be a number greater than 0.  If the route leads to destination and the gateway is the local host, count should be 0.  The default for count is zero.  The result is not defined if count is negative.

From the Linux 'info route' command:

Metric

The 'distance' to the target (usually counted in hops). It is not used by recent kernels, but may be needed by routing daemons.
