Sort posts by length of post title?

I have a client that wants to sort their posts by length of post title. She wants the links to the posts sorted into a triangle, with the shortest post title at the top.

I know, I know…

Is there some snippet of code I can add to the plugin files, or to functions.php that would give me that option in the Order by dropdown?

Thanks!
