I needed to sort the order of the products on a category page for a customer today in Magento and I wanted to post my solution.

Login to Magento admin and go to the Category where your products reside and click

Catalog > Manage Categories

Then click the category you want to edit on the left side. Once it loads click Category Products.

Now the last column on the right is called position. Just specify the order of your products here 1,2,3,4,5 etc.

Hope this helps.

Remember Log out and log back in then refresh your Magento Cache. System > Cache Management > Refresh All
