Sort tasks by task number

tl;dr - it would be great if there was an option to sort by task number

Our team's task list has grown quite large, and we are in the process of doing a full review of all tasks in Quire to get it down to a manageable size. It is taking multiple working sessions to do this, and a problem we are running into is that it's hard to pick up where we left off because the order of the tasks might change from week to week.

It would be helpful if there was an option to sort by task number so that we could easily put all the tasks back in the same order every time we go to do this.

Two alternatives I'm aware of:

1. No sorting. This will put the tasks in the order they were last left in. But if someone moves a task around, it's now in a different order.
2. Group by week created. Problem here is that sorting within the weeks isn't defined.
