I didn't think the Touch Cover was supposed to turn the screen on. Mine hasn't ever turned on automatically. Hmm...
With cover attached if you hit the Windows key the screen will come on.

Actually, I tried this and it still does'nt work. May have to pay a visit to the Microsoft store where I bought it and get their help.
When you close Touch Cover, the screen turns off. The cover helps protect the touchscreen while you’re in transit. When you open the cover, Surface RT wakes up. Press a key to wake up Surface Pro.
Waking up is normal behavior for the RT, but not for the Pro. There's nothing wrong with your Touch Cover
