The length of runway used for takeoff depends alot on airport altitude, (how high above sea-level is White Sands?), and "density altitude". The warmer the air, the less dense it is making it harder to get airborn. So given the combination of weight, and density altitude, I'm not surprised it took 12,000 feet.
