Putting all the advices together, with a few changes gives me:

use strict;
use warnings;
use autodie;

use Text::CSV_XS;

my $csv = Text::CSV_XS->new ({ binary => 1, auto_diag => 1 });
open my $fh, "<:encoding(utf-8)", "a.csv";
my @hdr = @{$csv->getline ($fh)};
my @arr;
while (my $row = $csv->getline ($fh)) {
    push @arr, $row;
    }
local $" = "\t";
print "@hdr\n";
print "@$_\n" for sort { $a->[1] <=> $b->[1] } @arr;
