In the playlist screen, now, there's the ability to 'Add Episodes'. In there you can choose which episodes to add and then how to sort them. One option for sorting is the 'Playback priority', and it can be sorted in either direction.
So, if you have podcasts you always want to hear first, you can set them as such when creating a playlist.
Hope this helps, let me know if I can answer anything else for you.
