Nope, you can't use pop, unless you use it like this: "@{[pop]}" .. The quotes turn it into a string instead of an integer, so the | does a bitstring or instead of a numeric or. If either of the operands are numeric, you'll get the numeric or:
perl -we 'print "000"|1'
1
that doesn't work for us, we need this:
perl -we 'print "000"|"1"'
100

and yeah, i came up with a handful of slightly different attempts that all came in at 55 too.

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).

or How to display code and escape characters
are good places to start.
