BlitzMax won't magically guess how you want to sort it. When sorting objects, it relies on the 'Compare' method to be able to give the relative order of 2 objects. You need to define this method.Something like:

Type blahType      'define the class
   Field x, y

    Method Compare%(other:Object)
        Local t:blahType = blahType(other)
        If t = Null Then
           ' Not of the right type, fallback on default comparison
            Return Super.Compare(other)
        Else
            ' OK, let's compare them, first base on x, then y
            Local diff% = x - t.x
           If x = 0 Then
                diff = y - t.y
           EndIf
           Return diff
        EndIf
    End Method
EndType
