Using zope.pagetemplate. ;)
More seriously, zope.pagetemplate has two parsing modes: HTML and XML.
Nobody actually uses the XML mode (pt files start with an <?xml?>
declaration, all tal/metal namespaces must be explicitly defined using
xmlns:tal=url-that-nobody-can-remember). The HTML mode allows you to
write Javascript just like you would do it in a browser, with no extra
XML-quoting:
<script type="text/javascript>
if (1 < 2) alert("it works!");
</script>
Does this not work for you? I'm currently looking at a Zope3 app that
does precisely this in its working page templates.

I seem to recall hacks of the form
<script ...>
// <![CDATA[
...
// ]]>
</script>
but I haven't seen one in a really long time.

I think scripts in XHTML were supposed to be XML-escaped. AFAIU
zope.pagetemplate was designed back when XHTML was supposed to be The
Bright Future of the Web.
