Sorting packages by ascending age results in a list of packages sorted from oldest to newest, while sorting packages by descending age results in a list of packages sorted from newest to oldest.
I find two related issues with this:
Firstly, the resulting sort order seems backward. Given that newer packages have a lesser age than older packages, ascending sort should be from newest to oldest, and vice versa for descending sort.
Secondly, the field name "Age" doesn't make it clear what age is meant: the time since the package was first submitted, or the time since the last update.

Please consider fixing the ascending / descending direction, and/or give the "Age" field a more descriptive name like "Last updated" or something.
