well going in the wrong direction might be progress..or not
here is your first row
40, 538974.187, 1222865.747, 96.86, scr
now the 2nd column looks like some easting (ie X )
the 3rd column looks like some type of northing, (ie Y)
so the question becomes, did you flip the X and Y values around?
or are these in feet or meters.
Are you about 1,222,900 meters from the equator (about 1,222 km-ish)
That will determine your confidence in the defined coordinate system
