The following does what you want. Note that I've excluded all 1 and 2-letter words, plus and and the. You may wish to add to the exclusion list. Also note that I have not provided for the situation where a paragraph word count goes over 999 for a 3-letter word. I didn't feel this was necessary. 
use strict;
use warnings;

my (%count, @pcount, @words, @values, $format, $i);

my @remove = qw/and the/; # Words to exclude
my $width = 10;           # Number of words to display

$/ = '-100';              # Line delimiter
while (<DATA>) {
    my %pcount;
    $_ = lc $_;
    while (m/[a-z]+('[a-z]+)?/g) {
        next if length($&) < 3;
        $pcount{$&}++; $count{$&}++;
    }
    push @pcount, \%pcount;
}

for (@remove) { delete $count{$_} if exists $count{$_}; }
@words = sort {$count{$b} <=> $count{$a} || $a cmp $b} keys %count;
$#words = $width - 1 if $#words > $width - 1;

$format = '%' . length($#pcount+1) . 's';
$format .= '%' . (length($_) + 2) . 's' for @words;

print ' 'x10, sprintf($format, '', @words), "\n";
for ($i = 0; $i <= $#pcount; $i++) {
    my @values = $i + 1;
    push @values, $pcount[$i]{$_} for @words;
    no warnings;
    print 'paragraph ', sprintf($format, @values), "\n";
}

push @values, $count{$_} for @words;
print "\n", ' 'x10, sprintf($format, '', @words), "\n";
print ' 'x10, sprintf($format, '', @values), "\n";
