Automated playlist with podcasts

I listen to many podcasts on my Samsung iAudio9 mp3 reader. I get these podcasts on iTunes. Currently, podcasts are ordered randomly when I paste them on my mp3 reader. I'd like to have them read according to my priorities. For example, if there is a new podcast for "L'?conomie en questions" I want to have it read first of all. Your software will read in a txt file (that I will be able to edit) which radio program to give priority to. It will check if there is a podcast corresponding to this radio program in my iTunes podcasts repertory. If so, it will add the name of the podcast (changing every week) in the playlist. And so on.
