Scott's solution worked for me, but is there any performance/security
benefit from Allen's suggestion?

Subject: Re: [nycphp-talk] How to sort a multi-dimensional array by a
given key?

Hi Tim,

array_multisort() should do the trick.  See the manual
(http://php.net/array_multisort) for some examples ("Example 256. 
Sorting database results") much like what you're describing.

Essentially, you'll have to loop through the array to create another
array something like:
	$sortDistance['SCID1']=>20
	$sortDistance['SCID2']=>10
and then call:
	array_multisort($franchises, $sortDistance);
