[iTunes] changing the order of podcasts

[Becca]

When I download segmented podcasts of Science Friday (or,more recently, BBC4's History of the World in 100 Objects, which is wonderful), they're in the list as most recent ones first... but I'd like to be able to play them in oldest one first. Is there any way to re-order podcasts in a list?

thanks!
