So you want to:
# ignore <script> tags on non-password protected pages
# honor <script> tags for all pages with edit password set

As you point out the problem with the RetrieveAuthPage approach is that 
for non-password protected pages everyone has edit access. Then in that 
case I think you'd need to check the password page attribute (refer to 
the answers on my post earlier today "Setting page privs from 
config.php"). You can do that by using code similar to what Hans suggested:

    $page = RetrieveAuthPage($pagename, 'read', true);
    if (!$page) echo "?cannot read $pagename";
    if ($page['passwdedit']) { DEFINE MARKUP }
