Variable valve timing on both the intake and exhaust sides now with 4 valves per cylinder would be my guess why they changed the firing order. They also incorporated a tubular type manifold (think headers) unlike previous cars that had cast-iron brick style designs.
Firing order can be used to better balance a motor to reduce vibration and noise, with all the new stuff on the 5.0 they can set the timing order to better fit with making more power vs compensating for NVH or noise.
