Just to be clear, you can already order those docs - however only hardcoded in the backend.
Just pass the desired orderby and order argument to the ShortCode (or let me know how you’d like to order).
Example:
order="DESC" orderby="menu_order"
Now set a menu order number in each of your docs to determine the precise order you want.
You can pass any valid WP Query order and orderby string argument (no arrays, of course)
However, I did understand you where asking for a front end order and sort by feature. That, is another story. This requires user input, to an URL parameter, which then gets read by code. This cannot be done that quickly (as explained in slack) mainly because it requires careful safety measures and also I have to think about how to do this both on the fly and on page reload respectively.
But if the only goal for now is a hardcoded backend ordering that forces those docs onto a certain order, you can do so.
Could we split this thread into a separate one to proceed? Because it is really about the proper content categorisation 
and was “resolved” here Proper content type and "categorisation" - #19 by anon66243189 (I did not even know we can continue discussion on resolved threads)
The key to effective and speedy implementation of things is the old and boring “one thing a time”, which heavily applies to “tickets” too haha.
