sorting podcast episodes on Zune

I have used MP3Tag to change my audio books to podcasts. Using the extended tags I have made sure the file name, title and track number fields all include track information. The track number field is formatted 01, 02, 03...

My problem is that when I go to the podcast on my Zune the tracks are sorted descending rather than ascending.

How can I have the podcast tracks sort ascending on my Zune?

Any assistance is appreciated.

Thank you.

So maybe you could try to add the "Published Date" and see if it sorts correctly ?
