Current version of iTunes is 11.
Update your phone to iOS 6.1.3 if you haven't already and you will have the current software. I'm not entirely sure if the customized vibrate for text tones, only incoming calls.

Check out the sound section of the iPhone.
Go to settings/sounds/text tone
In text tone, go to the very top and check the virbration pattern. If it is set to none, change it to your desired pattern.
If it is set to alert, I would back your iPhone up and restore.
