This is a FAQ:
Searching with Google or typing perldoc -q sort gives you How do I sort an array by (anything). You will need to split up your lines into separate items or at least extract the items for the comparison, for example by using
sort { substr($a,8,4) cmp substr($b,8,4) }
Please also show the code you've written. It is very hard to give you helpfull advice if we cannot see your code and have to guess as to what you have tried and where your problem might be.

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).
