Go to a user's works page – perhaps your own! – and follow the "Works in Collections" link. Or just go here: https://test.archiveofourown.org/users/testy/works/collected
The works should be ordered by the date that appears in the upper right corner of the blurb, with the most recent works on the top of the first page and the oldest works on the bottom of the last page.
The works are in no easily discernible order. (It's best match – this appears to be a side effect of AO3-5489.)
