You might try listening for distributed notifications associated with
shutdown and restart:

com.apple.restartInitiated
com.apple.shutdownInitiated
com.apple.logoutCancelled

(I found these on Leopard with Notification Watcher:

If you get a Quit after receiving either of the first two but without
having received the third, it's a Quit for a Shutdown rather than a
Quit just for the sake of quitting.
