TMTOWTDI,

I removed the superfluous, identical Step and acc key/value pairs throughout. I moved the wanted element to the centre of the @$data array. You'll need Perl v5.14 to use the s///r. There's similarities to other solutions using a Schwartzian Transform. 

#!/usr/bin/env perl

use 5.014;
use warnings;

my $data  = [
    { Color => 'black', Date => '01-05-2019' },
    { Color => 'blue',  Date => '10-11-2020' },
    { Color => 'green', Date => '08-06-2022' },
    { Color => 'white', Date => '01-03-2022' },
    { Color => 'red',   Date => '03-21-2021' },
];

my @sorted
    = map $_->[1],
      sort { $b->[0] <=> $a->[0] }
      map [$_->{Date} =~ s/(..)-(..)-(....)/$3$1$2/r, $_], @$data;

use Data::Dump;
dd $sorted[0];

Output:

{ Color => "green", Date => "08-06-2022" }
