Sandisk Clip Sport audiobook problem

So how does the Clip Sport sort the files, I have a book with 196 mp3’s and nothing I do fixes the ordering problem.

I have tried everything : 

-edited the mp3 tags of tracknumber 001-196. 

-edited the mp3 tags of title 001-196.

-edited all filenames 001.mp3 to 196.mp3, even that doesn’t work.

-I used software to change the dates ascending

-I copied all files to a new folder (where windows obviously sorts them perfectly) and copied them back.

Surely on of these should have worked, how is this acceptable?

I am left with the conclusion that NO ordering at all is going on.

Is there maybe old firmware that does work?

One large file is not an option for unless it syncs (like m4a in itunes).

This means this product is broken for me and I am about to return it because it CAN’T be used for audiobooks as advertised. Should have bought another ipod shuffle but it doesn’t have an sd slot.
