Well, if it's a one-off script, perhaps this is the time to learn Prolog, a language which does this sort of thing naturally:

#!/usr/local/bin/perl 
use strict;
use warnings;
use AI::Prolog 0.65;

my $by_two  = AI::Prolog->make_list(map { $_ * 2 } 1 .. 50);
my $by_five = AI::Prolog->make_list(map { $_ * 5 } 1 .. 20);

my $prolog = AI::Prolog->new(<<"END_PROLOG");
member(X,[X|Tail]).
member(X,[Head|Tail]) :- member(X, Tail).

one_hundred(A,B,C,D,E) :-
    or(member(A, [$by_five]), member(A, [$by_two])),
    or(member(B, [$by_five]), member(B, [$by_two])),
    or(member(C, [$by_five]), member(C, [$by_two])),
    or(member(D, [$by_five]), member(D, [$by_two])),
    or(member(E, [$by_five]), member(E, [$by_two])),
    is(100, plus(A, plus(B, plus(C, plus(D, E))))).
END_PROLOG

$prolog->query('one_hundred(A,B,C,D,E).');
while (my $results = $prolog->results) {
    print join(',' =>@{$results}[1 .. 5]), $/;
}
