wilcoxon_test, large number of points

I am not sure if this is the appropriate list, if not, I apologize.

I ran the wilcoxon_test.m on two sets of points (n=1022) with Octave
(v2.0.14 on ppc, v2.0.16 on i386) and I get the same "p" value

If I run the same data through Sigmastat I get a radically  different "p"
value of 0.14.

Is there a known problem with the implementation of the wilcoxon test in
octave?  Am I "missing" something?
