Action or script for saving files in Photoshop using text from clipboard as the file name

I make images for an online retail site and I've made several actions to make it go faster. I have an action that automatically saves multiple files for web using generic filenames such as "tee_XXX_Detail240x600". This action works great, but I must manually re-name these by replacing the "XXX" with the title of the design. It takes some time to do this, of course.

Is there a way to make an action or script that uses text from the clipboard to name the file? I tried recording the action while pasting the filename from the clipboard into the save box, but it didn't record it as I thought it might.

Thanks for your help.
