I suppose to fix it (maybe) you could create a modified version of
Reorient_Trans and when it does it's cross products, multiply one of them
by the sign of z so when z is positive, there is no change and when z goes
negative, one of the axis vecotrs gets reversed and the cross product
vector stays the same.

....or something like that.
