You *can* set the location of any stack, but unfortunately modal stacks are by default set to be centered over the stack that calls it (why? not sure…). So to get around it, you would need to set the loc in the preOpenStack of the stack that is going to be modal. If you want to specify it from somewhere else, you could do this:

on mouseUp
  set the uLoc of stack "MyModalStack" to 100,100
  modal "MyModalStack"  -- or 'open stack "MyModalStack" as modal'
end mouseUp

-- script of stack "MyModalStack"
on preOpenStack
  if the uLoc of this stack <> "" then
    set the loc of this stack to (the uLoc of this stack)
    set the uLoc of this stack to ""
  end if
end preOpenStack
