Then I would change your hash to: 

$counting{word}{$word}{str1}=$counter;
$counting{word}{$word}{str2}=$counter;

And then (see here for min function examples): 

foreach my $word (keys %{$counting{word}})
{
   print "$word\t", min ($counting{word}{$word}{str1},
                       $counting{word}{$word}{str2})
}
