You could try the "before" option to the pack method. I've not used it 
myself and I'm not sure it'll work.

Personally I would lay out all the buttons every time you remove or 
insert one. If you use the grid manager (which I usually use because it 
is more flexible than pack):
- keep the buttons in a collection, e.g.: a list of
   (button_name, button) so you can sort it by calling the sort method
- to add one, ungrid all in the current collection with grid_remove or 
grid_forget (the latter is fine in this case since you're not going to 
regrid it in the same place)
- add the new button to the collection
- grid all buttons in the collection
