I agree. I do not have a definitive solution, but I think we can do a 
few things to improve the situation:

- Change t_list output to show the task age instead of the creation date 
(which is not that interesting).

- Add an option to t_list to sort by age.
Hmm... (thinking aloud) if we multiply age with urgency, we get 
something quite similar to your patch. Maybe this is a better solution: 
add your sorting algorithm, but just not as the default one.
