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" }

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
