Steam Wishlist Price Filter is a userscript that adds the option to filter games by price or show only discounted items in your Steam wishlist. If you're interested in using/downloading the script, this page is probably what you're looking for.
Note: The script is currently broken and probably will remain that way because of the way the current wishlist page works. It might be possible to modify the script to support the new page, but it seems like a lot of work for relatively little gain, considering that the new wishlist page implements a lot of the same functionality as this script.
