NSArrayController & NSTreeController default sort order

I have a core data application working with my array and tree 
controllers, but I want to set the default sort order for the 
objects.  Currently each time I retrieve the data from the 
controllers the data comes back unsorted, and that is not good as I am 
displaying data in a sequence.  How do I set up the bindings correct 
so my controllers fetch the data pre-sorted?

Thanks in advance
