Considering that to sort, you have to retrieve the prices for all the rows 
in your table.

Wouldn't you be better off adding a price column to your DB, then running a 
separate script on a schedule to retrieve all the prices and update your 
table. Decide what the maximum age you can live with (is it the end of the 
world if the prices are 10 minutes old for instance?) and set the schedule 
accordingly.
