Drawback is if the Applescript is unable to connect as the VPN service is down or your internet connection is not ready yet. The alternative is to use an App which will also help you to keep the connection up and reconnect in case the VPN service drops the connection. A nice and new VPN auto reconnect app is "VPN Monitor" in the app store, it reconnects instantly the moment a VPN connection drops, is able to reconnect to a different VPN service if the preferred service is down, connects at start-up, keeps track of your downtime and uses a minimum of system resources to run in the background as a statusbar application.
