UNIX sorting - csv file

Hi,
Please help me to solve sorting in CSV file.
I have 25 columns in my CSV. (Delimiter is ",")
Summary columns are from 10 to 13 which are should not be sorted. From 1-9 and 14-25 should be able to sort in ascending. how should i do this using Sort command in unix.
If no simple commands pls suggest me, If I can sort only character field columns in the csv would be enough.

Thanks in advance!!
