Firstly, your array above looks somewhat suspect, you might want to use
actual code for your example.
That said, try the following:
$franchises = array();
$franchises['SCID1'] = array();
$franchises['SCID1']['BusinessName'] = 'SuperCoups of NY City';
$franchises['SCID1']['DistanceFromCustomer'] = 20;
$franchises['SCID2'] = array();
$franchises['SCID2']['BusinessName'] = 'SuperCoups of Buffalo';
$franchises['SCID2']['DistanceFromCustomer'] = 10;
uasort($franchises,create_function('$a,$b','return
strnatcmp($a["DistanceFromCustomer"],$b["DistanceFromCustomer"]);'));
