Mod Comment edit by bakunin: Please use CODE-tags for file contents too. It preserves whitespace which is often vital to understanding a files contents. Thank you.

You can use sort to sort for more than one key, in your case for second column first and for fourth column (in reverse order) second:

Code:
sort -t, -k2,2 -k4,4rn /path/to/your/file

Every line with a new value in the second field will be one of the lines you are interested in.

I hope this helps.
