A few bits of Perl.
Code:
perl -nalF, -e '                                  # set Perl to make tokens out of lines
BEGIN{$, = $" = ","}                              # output separators
$c[$o++] = $F[0] unless $col1{$F[0]};             # create a queue order
$col1{$F[0]}->[0] += $F[3];                       # add to column 4
$col1{$F[0]}->[1] += $F[4];                       # add to column 5
END{
    $col1{$c[0]}=["Sum of col4", "Sum of col5"];  # set header
    for(@c){print $_,@{$col1{$_}}}                # display tally
}' file.csv

Code:
col1,Sum of col4,Sum of col5
223,10,13
227,7,2
228,12,34

NAME
igawk - gawk with include files SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ... igawk [ all gawk options ] [ -- ] program-text file ... DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1). AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like @include getopt.awk in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path. OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports. EXAMPLES
cat << EOF > test.awk @include getopt.awk BEGIN { while (getopt(ARGC, ARGV, "am:q") != -1) ... } EOF igawk -f test.awk SEE ALSO
