Hi,
as far as I can see it in the manpages for Data::Dumper, it is not possible to do it like this.
You might have to write your own pretty-printer for that. Something along the lines of: 
#!/usr/bin/perl
use strict;
use warnings;
my $hoa = {a => [1,2],  'b'=>[1,3], c=> [2,0]}; 

foreach (keys %{$hoa}) {
    print "\t'$_' => [" . join(',', @{$hoa->{$_}}) . "],\n";
}

[download]
prints: 
    'c' => [2,0],
    'a' => [1,2],
    'b' => [1,3],

[download]
Regards,
