Each tab is one sort: five things to put in order by a number you don’t see, like year, weight or height.
Drag to reorder, then check. Anything in the right place locks. You have four checks per sort.
Every list hides one surprise, like the fax machine being older than the telephone. The numbers appear when you finish.
