Sorting inside a sorted list?

I only sort the array one time depending in which order the user wants the output (upwards/downwards).

Your code doesn't work for me, but I managed to take some math out which is good. Thanks for the hint.

    Method compare:Int(v:Object)
        If sortdfa_type(v).z = z Then
			Return sortdfa_type(v).id-id
        Else  
			Return sortdfa_type(v).z-z
        EndIf 
	EndMethod
