Try this awk script...
Code:
ls -1t *.csv | awk -F"_" '{
    x[NR] = $3
    y[$3] = $0
} END {
    for (i=1; i<NR; i++)
        for (j=1; j<(NR+1-i); j++)
            if (x[j] > x[j+1]) {t = x[j]; x[j] = x[j+1]; x[j+1] = t}
    for (i=1; i<=NR; i++) print y[x[i]]
}'

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).

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
