[Papervision3D] as3 for each randomization

[xero]

hey list.
this isnt exactly a pv3d question
but it is related to a pv3d project,
so here goes...

im using flex actionscript3... i got a

foreach (var i:* in object.geomerty.vertices) {
   //do stuff
}

this loop takes me threw the vertices in
their numeric order (from top to bottom i think)

i was woundering if their was a way to randomize
this, but still hit all the vertices. i was using a
multi-level array, and could have used array.sort
but then i found out about the i.extra = {1=bla, 2=bla, 3=bla};
which is much faster w/ a foreach...

any ideas?
thanx again guys
