The sort options mean the following,
-t/ : split fields on the / character
-k2,3r : First, reverse (r) sort on the string that consists of fields 2 to 3 , which is root/path[12] in the example
-k1,1rn : Then Do a reverse numeric sort on the first field which is the file size
-k4 : Everything sofar being equal forward sort the remaining fields (file names).

Hope this helps..
