sort comma separated lines by specific columns

Hello,

I have a file which lines' words are comma separated:

Code:
aa, bb, cc, uu b, ee, ff
bb, cc, zz, ee, ss, kk
oo, bb, hh, uu a, xx, ww
tt, aa, dd, yy aa, gg

I want to sort first by second column and in case of tie by fourth column with sort command.

So the output would be:

Code:
tt, aa, dd, yy aa, gg           
oo, bb, hh, uu a, xx, ww
aa, bb, cc, uu b, ee, ff
bb, cc, zz, ee, ss, kk

Tried with:

Code:
sort -t, -1 +2 -3 +4 -5 file

But seems not to work.
Thank you

CUT(1)							      General Commands Manual							    CUT(1)

NAME
cut - select out columns of a file SYNOPSIS
cut [ -b | -c] list [file...] cut -f list [-d delim] [ -s] OPTIONS
-b Cut specified bytes -c Select out specific characters -d Change the column delimiter to delim -f Select out specific fields that are separated by the -i Runs of delimiters count as one -s Suppres lines with no delimiter characters, when used EXAMPLES
cut -f 2 file # Extract field 2 cut -c 1-2,5 file # Extract character columns 1, 2, and 5 cut -c 1-5,7- file # Extract all columns except 6 DESCRIPTION
[file...]" delimiter character ( see delim)" with the -f option. Lines with no delimiters are passwd through untouched" Cut extracts one or more fields or columns from a file and writes them on standard output. If the -f flag is used, the fields are sepa- rated by a delimiter character, normally a tab, but can be changed using the -d flag. If the -c flag is used, specific columns can be specified. The list can be comma or BLANK separated. The -f and -c flags are mutually exclusive. Note: The POSIX1003.2 standard requires the option -b to cut out specific bytes in a file. It is intended for systems with multi byte characters (e.g. kanji), since MINIX uses only one byte characters, this option is equivalent to -c. For the same reason, the option -n has no effect and is not listed in this man- ual page. SEE ALSO
