Sorting with Infinity


Hi group;

I construct lists which may look like this

	{7,-2,-Infinity,Infinity,1}

When this list is sorted by using Sort, I get

	{-2,1,7,-Infinity,Infinity}

I would prefer, naturally, 

	{-Infinity,-2,1,7,Infinity}

This is easy to do if one doesn't care about elegance.  Without 
spelling out the obvious details, here are a few kludges:

(1) Replace Infinity by 10^15, Sort  then switch back to Infinity.
(2) Use Append and Prepend after Sort and  deleting infinities.
(3) RotateRight after Sort and switch signs on infinities

Anyone got a "cute" solution say by using a sorting function or 
perhaps some arcane command unknown to mere mortals? 

Jack
