I have this small HTML document:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<html>
    <head>
        <title>HTML Test</title>
        <script type="text/javascript" src="jquery-1.3.2.min.js"></script>
        <script type="text/javascript">
            $(document).ready(function()
            {
                $("script").each(function()
                {
                    if($(this).attr("type") == "code")
                    {
                        alert($(this).text());
                    }
                });
            });
        </script>
    </head>
    <body>
<script type="code">
var Text = "Text";
</script>
    </body>
</html>
When run using Firefox the alert displays the text contents of the <script type="code"> tag. When run in IE8 it displays nothing.
Do you know why? I'm stumped.
You might have more luck with .html() and if that doesn't work try this.innerHtml. I did not test this however.
I do have another tip for your code however. If you want only scripts of type code you can have a single selector instead of having to check the attribute in the loop:
$("script[type=code]").each(function() {
    alert($(this).html());
    alert(this.innerHtml);
});
