Touch Sort by Series

Hi all

I sort one thing and suddenly another pops its head above the parapet.

I've loaded my books to my (now working) SD card. I had everything sorted using the sticky regarding shelf management but, for some reason, my series numbers are, now, listed in reverse.

For example, my Aurelio Zen Mysteries collection, the books, which have the series number followed by the book title, are in reverse order, ie: 'End Games' which is book 11 is the first in the list and 'Ratking', book 1, is listed last.

I know there's a way to rectify this, but, for the life of me, I just can't seem to remember how.

Thanks in advance for the help.
