Narrative:

After landing on runway 9R I was cleared to cross runway 27R and hold short on the north taxiway. I mistook the controller's directions and thought I was to cross runway 36 and hold on the taxiway to the north of that. The controller advised me that I had crossed the wrong runway. I promptly taxied off the runway I was crossing and held short on the other side. The factors, I believe, that caused this incident were my inattn to the controller's directions and my orientation in relation to runway 9R or runway 9L, as I mistook runway 27R as being the crossing runway (which was runway 36). Fatigue also may have been a factor since I was up quite early that day.
