Ah. You've clarified what you mean a bit.

Ok, Here's a simple version that is limited to finding the top five (so it will fit across one standard terminal screen). Adjust $limit and redirect to a file for larger numbers.

Not necessarily the best way, but not too bad:

use warnings;
use strict;
$/ = '';

my $word = qr/(?<!\p{Alnum})\p{Alnum}+(?!\p{Alnum})/;
my %count;
my $paragraphs;
my $counter;
my @results;
my $limit = 5;

while ( my $line = <DATA> ) {
    while ( $line =~ /($word('$word)?)/g ) {
        $count{$1}{count}++;
        $count{$1}{$.}++;
        $paragraphs = $.;
    }
}

for ( sort { $count{$b}{count} <=> $count{$a}{count} || lc $a cmp lc $
+b } keys %count )
{
    last if ++$counter > $limit;
    push @results, $_;
}

print ' ' x 12;
printf "|%12s", $_ for @results;
print "\n";
print 'Total count:';
printf "|%12s", $count{$_}{count} for @results;
print "\n";
print '-' x ( 13 * ( $limit + 1 ) ), "\n";

for my $line ( 1 .. $paragraphs ) {
    printf "Prgrph %4s:", $line;
    printf "|%12s", $count{$_}{$line} || '0' for @results;
    print "\n";
}

__DATA__
"Hello World!"
"Oh poor Yorick, his world I knew well yes I did"
"don't won't, can't shouldn't, you'll, it's, etc."
"Señor Montóya's resüme isn't ápropos."
