I would guess that the problem is that they share the same name. I don't
know if you can have CGI.pm help you, but OTOH it's not that difficult
to grab the values:

my @cookie_values;
for my $pair ( split /;\s*/, $ENV{HTTP_COOKIE} ) {
my ($name, $value) = split /=/, $pair;
s/%(..)/chr(hex $1)/eg for $name, $value;
push @cookie_values, $value if $name eq 'var';
}
