If I had that level of axial runout, I'd take the rotors off, polish up the mounting flanges and then remeasure them. The excess is very small and a little rust or even anti-seize compound between the faces would cause it.
However, I'd definitely measure the radial runout as well. Instead of measuring the face of the rotor, measure the outside edge to see if the rotor is off-center on the hub.
