I wasn't sure what it was, but when braking at low speed it feels like the ABS is engaging. (The brake pedal shudders.) I thought it might be warped rotors but I read the info from stoptech and it seems that there is no such thing. Anyway . . . I took another look at the brakes and this time I checked out all four. The pic is of the driver side front, which is the only one with the scoring. What might this be?

something caught in between the pad, could be down to the sensor..

You've got something between the rotor and the pad (though it may not be there anymore) or a severely worn out pad. I think you're misunderstanding the StopTech brochure, though. They're probably talking about uneven depositing of pad material on the rotor resultant of improper break-in; but, absolutely, rotor can warp when they dissipate high heat and cool unevenly.
