Adding a reset.css before drupal core module css files

Hi all,

I am working on creating a base theme to build any future work on.
Elements will include bits of:
Zen theme
Hunchbaque theme
Sympal Theme
Blueprint CSS framework.

In order to add the reset.css component of blueprint.css,
I need that stylesheet to get added before drupal adds module css files.

I have a function in my template.php file that I use to add all the css.

function bluezen_styles() {
  drupal_add_css(path_to_theme().'/css/lib/typography.css', 'theme', 'all');
  drupal_add_css(path_to_theme().'/css/lib/grids.css', 'theme', 'all');
  drupal_add_css(path_to_theme().'/css/lib/buttons.css', 'theme', 'all');
  drupal_add_css(path_to_theme().'/css/lib/print.css', 'theme', 'print');
  drupal_add_css(path_to_theme().'/css/layout.css', 'theme', 'all');
  
  $css = drupal_add_css();

  $reset = path_to_theme().'/css/lib/reset.css';
  $css[all][module][$reset]= 1;

//  array_unshift($css[all][module],($reset=>1));

  
  return drupal_get_css($css);
}

This does a great job of adding all the extra css files.
The tricky thing is getting the reset.css file adding to the beginning of the $css array.
The code displayed above only adds in to the end of the $css[all][module] array.
array_unshift seems to be the correct function, but I can't get that to work.

As a workaround, I have added it in as regular HTML above the

print $styles

in my page.tpl.php.
However, this means it isn't included in the CSS aggregator.

Thanks for any tips,

Regards
Alan
