FWIW recent cards allow connecting 3 or possibly even 6 screens with the  
outputs being numbered at random by the driver (no apparent pattern,  
depends on card make, model, revision, ..)

To get predictable behaviour XMonad should detect the virtual screen layout  
using xrandr and present the screens in order derived from the place they  
appear in the virtual screen.

You possibly could make a script that numbers your outputs by calling  
--primary as many times as there are screens to shift each screen to the  
top in order but there is no guarantee that this will give you any  
particular order, only that the "primary" is first.

Maybe I could try with 3 screens to find out if the order is just rotated  
or if you can really get the screens in different order.
