You might also want to check that the interface is up.

My personal hack (not for a VPN, but for "being online", which turns my ssh 
tunnels on and off) is to look in the output of "netstat -rn" for a default 
route. This may imply that an alternative test for you is to test for a route 
to your VPN's address range?  Just an idea.
