sort.js undefined

When altering the CKEditor appearance on an existing or new profile a javascript exception prevents you from dragging/ordering buttons on the toolbar configurations.

Uncaught TypeError: undefined is not a function
sort.js:line 47

I've tried setting jQuery update to 1.7 on both the latest version (7.x-2.4) and the development version (7.x-2.4dev+5) with the issue persisting.

Does anyone else have this issue, and could anyone post a working versions list of CKEditor and jQuery_update (including jquery update settings) ?

Edit: I've since tried using this without jquery_update enabled, default Drupal jQuery 1.4.4 and jQuery UI 1.87 versions also cause this to happen.
