Call for Price sort order

Ok the problem I am having is that I have a few call for price products in the same category as products that have a price. I want the default sort order to be from lowest price to highest, BUT that means that because I have products that are set to "Call for Price" which are essentially set to $0 which puts them at the top of the product listing every time. Is there a way to have the Call for Price products show up last while still maintaining the sort order of lowest to highest?

You should be able to force them to the bottom using the 'sort order' option - the Call for Price products set to a high number, and all the rest (with prices) all to the same (lower) number.

In other words, set the Call for Price products to sort order 99, and all the other (priced) products to sort order 1.

If you are referring to the sort order option on each individual product, I already tried that. I left all the products with a price at sort order "0" and changed the ones with call for price to 99 and it does nothing. I think that the sort order on the individual products is depreciated as the option in configuration->product listing is the one that controls it ultimately. Any other ideas? This is a real problem! Thanks for the input though.
