I'm sure this is simple but I can't figure it out. I have a list of strings like this(after using sorted on it):
Season 2, Episode 1: A Flight to Remember
Season 2, Episode 20: Anthology of Interest I
Season 2, Episode 2: Mars University
Season 2, Episode 3: When Aliens Attack
....
Season 3, Episode 10: The Luck of the Fryrish
Season 3, Episode 11: The Cyber House Rules
Season 3, Episode 12: Insane in the Mainframe
Season 3, Episode 1: The Honking
Season 3, Episode 2: War Is the H-Word
How can I make them sort out properly? (by episode #, ascending)
