I can think of two simple methods that will allow you to tell if 
"the center screw is ground".

First, turn the circuit breaker off that controls that outlet.  You can 
simply plug a light in the socket and verify that it goes off when the
proper circuit breaker is shut off.

Remove the wall plug face plate (remove the center screw).

Examine the inside of the wall box.  If it is grounded, it will have a bare
copper wire connected to a screw that is attached to the wall box.


Second method:

Most discount hardware stores have a wall outlet checking device.  It is 
simply plugged into the outled.  There are a couple of color coded LEDs
on the device that will tell you if the outlet is wired properly and
if ground is REALLY there.

'That's my two cents.
