I found I had to use extra tension with the quick release on my bikes with horizontal dropouts. (steel frames).
If I didn't then the wheel would slew over when climbing steep hills.
Fit the wheel in the frame with the axle as far back as it will go.
(touching the back of each dropout.)
Now measure the distance from the center of each end of the axle to say the front edge of the bottom bracket.
What you are trying to do is make sure the drop outs are square to the frame.
ie: Is one side longer than the other?
From what you are saying, it sounds like one side is around 1/2" out.
The only other option, if the dropouts are square, I guess the dish of the wheel could be wrong?
Turn the wheel round and check again to see if it's the same or the offset/angle has reversed.
You could also check for symmetry of the rear end.
