Classic learning-to-theme-Magento question!

The relationship of one block to another is most evident in templates (as your current effort demonstrates). The ability for a parent (footer, in your case) to trigger rendering of another block requires that a parent-child relationship be established. This typically happens in layout update XML.

If this relationship were core, it is likely that you would see the following in the base/default theme's layout/page.xml file:

<block type="page/html_footer" name="footer" ...>
    <!-- other child block directives -->
    <block type="page/template_links" name="top.links" as="topLinks"/>
</block>

In your case, because you are adding a relationship between two existing blocks, you can set up a relationship between block instances in a special end-user layout xml file named local.xml which you should place in your custom theme's layout folder. Here is what it should look like:

<?xml version="1.0"?>
<layout>
    <default><!-- effectively: "do this on all pages" --> 
        <reference name="footer"><!-- parent block -->
            <action method="insert"><!-- this PHP class method sets the relationship -->
                <block_name_to_insert>top.links</block_name_to_insert><!--use the block name in the layout, not the alias. See Mage_Core_Block_Abstract::insert() -->
                <sort_relative_to_other_childname/><!-- empty val is fine here -->
                <sort_before_or_after/><!-- not relevant -->
                <alias>topLinks</alias><!-- because you are using the original alias, need to re-specify that here -->
            </action>
        </reference>
    </default>
</layout>
