For each specific page that requires an additional stylesheet, do they have their own page type, in other words, are they not just of the default "Page"?
If they have their own page type, you can tell the controller to add an additional stylesheet into the <head> of the HTML document, without adding it to the template itself.
<?php
class MyPage extends Page {
...
}
class MyPage_Controller extends Page_Controller {
function init() {
parent::init();
Requirements::themedCSS('MyPage');
}
}
?>
Then, if you access a page that has "MyPage" applied to it, the MyPage.css file will be added, provided that it exists within the theme you're currently using! It should also appear after the themedCSS() stylesheets that are set on Page.php, so you don't have to call !important all the time.
Alternatively, the $URLSegment on the <body> element would work if you're just using the page-type of "Page" for all your pages, as Will said, but it's a bit fragile, as the URLSegment value can change when someone changes the title of a page.
My suggestion would be that if you haven't already, create the additional custom page types like the example above, and apply it to any page in the CMS that requires a specific stylesheet. Create an additional page type for any page that requires a separate stylesheet. This would be the optimal solution, rather than relying on $URLSegment being a correct value.
