Sure:

Code:
-t,                  Use a comma as the field separator
-k1,2                Specify fields 1 and 2 as the primary key
-k3.7,3.10           Specify the 7th character through the 10th character of field 3 as the secondary key ( the year )
-k3.1,3.6            Specify rest of field 3 as the 3rd key
-k4                  Specify field 4 through the last field as the 4th key..

A numerical sort is not needed since the date parts are fixed length.
