I want to load an external script in <head>. It is module specific so I want my module to take care of the loading.
In Drupal 6, function drupal_add_js() does not allow to add an external script in <head>. It will be available in Drupal 7 passing the "external" argument to the function. In D6, I can use drupal_set_html_head() instead, but it inserts the given data in the beginning of the <head> which I don't want. I'd like to append data in it.
It turned out that drupal_html_set_head() appends data.
$stored_head .= $data ."\n";
So the behavior I experimented--data was inserted in the beginning of head data--should come from that I call drupal_html_set_head() in my module's hook_init() function.
How can I append data to the very and of <head>?

The default page.tpl.php (you can find it in /modules/system/page.tpl.php is this:
<head>
<title><?php print $head_title; ?></title>
<?php print $head; ?>
<?php print $styles; ?>
<?php print $scripts; ?>
<script type="text/javascript"><?php /* Needed to avoid Flash of Unstyled Content in IE */ ?> </script>
</head>
When you make drupal_set_html_head() it is appending stuff to variable $head, but still there are more variables appended as you see.
One possible solutions is to append the stuff that you want to $scripts, instead of $head.
How?
with a preprocess function from your module:
function MYMODULE_preprocess_page(&$variables) {
$variables['scripts'] .= $your_stuff;
}
I didn't try this solution, but if doesn't work maybe is because the order of execution. Try to set your module's weight higher, so it will run after the system_preprocess_page.
Other reason why may not work is because the theme is printing the variables in different order in page.tpl.php. But you can't control this from the code of a module.
