Multiple criteria in one loop

Hi,

I have posts in a category that contain the word Season 1, Season 2, Season 3 etc. And some categories go up to Season 30. I want to write a loop which detects the highest season number and will then display the results sorted by season.

This is what I have so far:

[code moderated - for any code longer than 10 lines, please use the http://pastebin.com/ - see http://codex.wordpress.org/Forum_Welcome#Posting_Code ]

$catymeta is the category number of the posts that need to be displayed. It is set using a custom field.

The only problem with this is that I would have to repeat the code to display Season 2+ and if a category doesnt have any posts with the word Season 2 in the title the Season 1 and

will remain there.

So really what I want is to run a query that outputs like this and that goes to the highest season number...

Season 1

1. Season 1 Episode 1
2. Season 1 Episode 2
3. Season 1 Episode 3

season 2

1. Season 2 Episode 1
2. Season 2 Episode 2
3. Season 2 Episode 3

I hope I am making myself clear. Any help is greatly appreciated.

Thanks
