{tags} - just unsorted

Hello,

I've got a book that, in the metadata view, has tags like this...

"Science Fiction, Postapocalyptic"

So, the first tag is "Science Fiction". Unfortunately, when using {tags}, the list is sorted alphabetically, thus making "Postapocalyptic" the first one.

Is there any way to get the original, unsorted tag list, since then I want to use this first tag (the one, I entered first, not the first one alphabetically) as a part of my ebook name on my device (tolino collections -> collection should be series, if any, first tag else or "other" if no tags/series... Works fine, except the tags are sorted, thus I keep getting the "wrong" tag).

Regards,

Flo
