Why?
From sort,
The comparison function is required to behave. If it returns inconsistent results (sometimes saying $x1 is less than $x2 and sometimes saying the opposite, for example) the results are not well-defined.
It doesn't say undefined behaviour, so I guess you're in the clear as far as not crashing is concerned?
That said, the "quality of the randonmess" can change at any time. sort's algorithm has been changed before, and could change again.

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).
