Report Builder Calculated fields

Does anybody know how the calculated and aggregate fields are sorted? When you click on either of the fields to view or edit your list, they are listed in a certain order.

They are not in alphabetical order and I don't think they are in the order you create them because there are times when I create a new entry and it goes to the bottom of the list. After I save and exit, I will open it again and notice that the new entry has been sorted differently.

Any ideas?
