What are the some of the more Perlish ways to rephrase that if statment?

Here's an alternative solution without a regexp/match condition. It's not intended to be 'more' perlish but 'differently' perlish. TMTOWTDI and all that.

#!/usr/bin/env perl

use strict;
use warnings;

# in my own code I would use Readonly to define these constants
# -- http://search.cpan.org/~sanko/Readonly-2.05/lib/Readonly.pm
my $idx_usage = 4;
my $idx_mount = 5;

my @input = (
    '/dev/dsk/c0b0t0d0s4 12209400 5496486  6712914  46%       /home',
);

printf "cap = %s\n", parse_capacity(@input);

exit 0;

# -----

sub parse_capacity {
    # use $_[0] or shift @_ instead of my ($scalar) = @array;
    my $df_output = $_[0];

    my @fields = split /\s+/, $df_output;

    if ($fields[$idx_mount] eq '/home') {
        my $use = $fields[$idx_usage];
        chop $use; # remove '%'

        return $use;
    }
    else {
        return 'Match Error';
    }
}
