You need to specify that the field can accept the drop. Try adding the  
following code to the field script after commenting out the  
dgTrackDragReorder code:

on dragEnter
     if  line 1 of the dragData["private"] is "MyData" then
         set the dragAction to "copy"
     end if
end dragEnter

on dragDrop
     put line 2 of the dragData["private"] into me
end dragDrop

Does that work?
