Select any email list, where you have a count (e.g. 1 - 100 of 300).
Hover on the count to see a drop down showing the options Newest and Oldest.
This will sort the email in that list by date - newest first, or oldest first.
Where there is only a estimate (eg 1 -50 of many) it is an indication that Gmail has not yet counted all your email in the chosen list and the sort option will be greyed out.
