That looks like a candidate for some light weight OO and named parameters. Consider:

use strict;
use warnings;

my $obj = bless {flibble => 1, floop => 2, flop => 3};

$obj->work(nuts => 7, bolts => 5);

sub work{
    my ($self, %params) = @_;

    $self->more_work(%params);
    print "$params{nuts}\n" if $self->{flibble};
}

sub more_work{
    my ($self, %params) = @_;

    $self->even_more_work(%params);
    print "$params{bolts}\n" if $self->{floop} > 1;
}

sub even_more_work{
    my ($self, %params) = @_;
    my $sum = $params{nuts} + $params{bolts};

    print "$sum\n" if $self->{flop} == 3;
}

Although in real code a constructor would check important parameters and subs would check that any required named parameters are as expected.

True laziness is hard work
