I want to be a brain surgeon but, for the time being, I'm happy to be a nurse.
It shows that you have a desire/plan for something in the future but that, at the moment and for the foreseeable future, something else is true.
With your sentence, the only way I can see to incorporate it would be something like: At the end of the oral proceedings on Oct 10, 2008, the plaintiffs sorted out their requests. Their requests will remain the same for the time being.
This shows that there is a possibility that they will reorganise them in the future.
Basically, because "for the time being" involves the present and potentially moving into the future, it can't really be used with the past tense, as you did (sorted out their requests).
