I have an array that looks something like this:

Array
(
    [Erik] => Array
    ( 
        [count] => 10
        [changes] => 1
    )
    [Morten] => Array
    (
        [count] => 8
        [changes] => 1
    )
)

Now, the keys in the array are names of technicians in our Helpdesk-system. I'm trying to sort this based on number of [count] plus [changes] and then show them. I've tried to use usort, but then the array keys are replaced by index numbers. How can I sort this and keep the array keys?
