Reading the docs I would try

use Archive::Tar;
my @properties = qw( name size mtime );
my $location = "/vol/archive5/test5.tar";
my %files = Archive::Tar->list_archive($location,0,\@properties);
print Dumper \%files;

UPDATE: my posted code seems to work...

UPDATE: the output looks funny though:

$VAR1 = {
          'HASH(0x3148770)' => {
                                 'mtime' => 1351116756,
                                 'name' => 'SuffixTree-0.07/t/test_str
+ing.t',
                                 'size' => 742
                               },
          'HASH(0x2f9e870)' => {
                                 'mtime' => 1351116816,
                                 'name' => 'SuffixTree-0.07/suffix_tre

                                 'size' => 6075
                               },
          'HASH(0x3148410)' => {
                                 'mtime' => 1351115894,
                                 'name' => 'SuffixTree-0.07/t/13-kwali

                                 'size' => 691

Design-wise, an array of hash references would make more sense imho.
