There is no such thing as an outlet installed upside down.
The NEC does not currently specify which way up the ground has to be.
Many times the engineers will specify grounds up for the reasons stated.
Also many believe that having the ground up could deflect any metal objects that slid done the wall. No doubt that is a possibility.
Joe T. has a picture of a stainless steel duplex plate that the screw fell out of the plate and the plate fell across the neutral and hot prongs.
If that outlet had been installed ground up and the plug in the outlet had a ground prong the plate would have been caught by the ground prong.
I work for a very large electrical contractor in the interest of all employees doing things the same way we have a 'grounds or neutral up' policy.
If we install the outlet horizontally the neutral is 'up'.
