Try this:

<customer_account>
    <reference name="customer_account_navigation">
        <action method="addLink" translate="label" module="customer">
            <name>yournamespace_yourmodule</name>
            <path>module/controller/action</path>
            <label>Label</label>
        </action>
    </reference>
</customer_account>
