Comment 2 for bug 660164

Mind you, if I scan as decribed above I keep the stack in its original order when putting it in the sheet feeder again, so the second run (back pages) goes from the high numbers down.
The order of pages in simplescan is thus F1F2F3F4F5B5B4B3B2B1 F=front, B=back (not F0F1F2F3F4B0B1B2B3B4 as in #660253)
It's a minor issue sorting-wise but the stitching must take this into account of course, not to defeat its very purpose.
