Purchased ringtone won't work for text messages

[iJeff1966]

We bought two ringtones, both short, they are from Despicable Me "He's so fluffy, I wanna die" and "It's so fluffy", both purchased from iTunes. They work on my phone for incoming calls and messages but curiously they will only work for incoming calls on my wife's phone. I have looked at every setting I can think of but can't get them to work for messages, I have to be missing something.
Any thoughts?

Thanks!

Edit:
When either of the tones are set for Messages on wife's phone it does not vibrate when receiving a message (vibrates with any other ringtone).
