There is this script:
Which allows you to either go by SRS level ascending or descending (i.e. you cannot pick the level freely like in Ultimate Reorder, but you can either work your way up from Apprentice 1 or down from Enlightened). It is … semi-compatible with Ultimate Reorder - that means, most of the time you can run them both and they don’t interfere too much, and the script whose ordering mechanism you used last will gain precedence over the other, so that you can switch between the two scripts in one session (but they don’t overlay each other, e.g. you cannot sort by level inside apprentice 1 items as far as I remember).
One downside of the two-script approach that I sometimes bumped into was that I could not make the Reorder script actually reorder the input queue, so I could not defer a given item if I wanted to think about it for some more. Therefore I ended up disabling the Reorder Buttons script again a few days ago (but I will definitely reenable it again if I end up having a pile of reviews once more 
).
