From what i have understood from: http://en.wikipedia.org/wiki/Parity_of_a_permutation If in Figure-40.5, i take [0,2,3,1] as a positive orientation i will get clockwise orientation for the shared face when viewed from v31 since the order will be [u,w,v31,v]. But for ordering [0,1,2,3] it is counter-clockwise(as shown in that figure).
