Page-Cat-List is a WordPress Plugin (surprise) that you can use for generating a sorted list (where you can/must 
define the order) with items from pages and categories. That’s the whole story. Unfortunately WordPress does not 
implement this in its core-functionality so I had to build that on my own.
As of writing this Page-Cat-List supports:
<ul>
<li>mix category- and page-items and display them in one list</li>
<li>sort these items (first level only)</li>
<li>define a title</li>
<li>define a maximum depth</li>
<li>define a html-id for the first ul-element</li>
<li>most of the stuff you can do with get_pages and get_categories arguments:
<ul>
<li>exclude items</li>
<li>include items</li>
<li>etc. pp.</li>
</ul>
</li>
</ul>
