Well, it works for me. Of course, there are some strange things afoot. First of all, my copy of LWP::Simple only returns one scalar from its get() method:

my @html=get("http://setiathome.ssl.berkeley.edu/stats/team/team_2414.
+html");
print "Number of lines: ", scalar(@html), "\n";

That prints Number of lines: 1. You probably need a split in there to make a real array, or else some other kind of regular expression to pull out your stats:

#!/usr/bin/perl -w

use strict;
use LWP::Simple;

my $line = get("http://setiathome.ssl.berkeley.edu/stats/team/team_241
+4.html"); 
$line =~ s/\cM//g;
$line =~ s/<(br|p)>/\n\n/ig;
$line =~ s/<(?:[^>'"]*|(['"]).*?\1)*>//gs;
if ($line =~ m/(\d+\)\sHelmet\s\d+\s+([\d.]+\s\w+\s){5})/) {
    print $1;
} else {
    print "Not found\n";
}

Hardly beautiful, but the results speak for themselves:

4) Helmet
119
1890 hr 58 min

That said, there are HTML parsing modules available on CPAN, especially ones dealing with tables. I would prefer that than dealing with the regex.
