I can make a button generate a random query for you each time it's clicked. It requires that you add foo_jscript_panel to your layout...

The script...

It uses javascript rather than title formatting for the random number generation. The relevant bit of code is right at the bottom of the script.
For testing title formatting, I generally use the status bar preview in the main preferences or you can mess around with this..
