Sorting complex points


Hi all,

I'm trying to sort lists of random complex points on the unit circle 
using their angles as criterion to sort them: I mean, if
z=Cos[a]+I*Sin[a] and w=Cos[b]+I*Sin[b]( 0<=a,b<2*Pi ),
I want z<w if a<b;

how can i do that?

I tried to define Angle[z] as a piecewise funztion, but I still don't 
understand how to use it with Sort...

Thanks,

andrea
