Dunno, but I'd search for "Normal Scores Test", AKA van der Waerden's 
Test, in books dealing with nonparametric tests.  It comes out in a 
natural way as the score test in a model  where you assume that you have 
normally distributed data with a location shift, but transformed by an 
unknown monotone transformation.
