This doesn't sort the hash, it only converts the date from D/M/YYYY to YYYY/MM/DD so that it can be used as a key in your %datecount hash. This hash can be sorted the way you do it in your code fragment.
As to qw:
$ perldoc -f qw
qw/STRING/
Generalized quotes. See "Regexp Quote-Like Operators"
in perlop.
It returns a list of words without doing interpolation on them. It is just a convenient way of writing:
my @dates = ('5/7/2001' '3/10/2005' '1/1/1996' '2/1/1993');
Hope this helps, -gjb-

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).
