Hi opaltoot,
tybalt89 already gave you the answer, I just wanted to note you can use B::Deparse to see how Perl interprets your code for yourself (I replaced 1 with $x to prevent optimization):
$ perl -MO=Deparse,-p -e '$x ? $a = 2 : $b = "x";'
(($x ? ($a = 2) : $b) = 'x');
$ perl -MO=Deparse,-p -e '$x ? ($a = 2) : ($b = "x");'
($x ? ($a = 2) : ($b = 'x'));
See also Operator Precedence and Associativity.
Although you might want to consider if using the ternary operator like that will help the legibility of the code :-)
Hope this helps,

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
