This approach will not give the correct result if all of the values are negative: 
my %hashName = (a => -1, b => -2, c => -3);
my $max = 0;
$_ > $max and $max = $_ for values %hashName;
print $max;
__END__
0   # expected -1

Of course, if you are sure that all values are positive numeric values, there is no problem. But it is something to keep in mind in general, I think.
