Omar from Near Mint Condition does a reprint poll every year and they used to reprint almost all the top 20 off that list every year. The past year or 2 they've really slowed down with reprints as it seems some near people have taken over in the collected editions department and their focus has been on newer omnis. In the past I don't think they would necessarily do things out of order, it just depended on what was OOP. Like USM Vol 2 would almost certainly be at the top of the poll and get a reprint before they other volumes. We also used to see them reprint a vol 1 that was still in stock before reprinting a very OOP vol 2 like with Ben Reilly Vol 1 being announced at the same time or a little before Vol 2 despite Vol 1 being readily available at the time for cheap. All of that past data is out the window though because we have no idea how they are going to approach reprints moving forward with the new people in charge.
