您可以使用操作addTabAfter代替addTab，然后必须指定<after>参数(类别，网站，追加销售... ).

You can use the action addTabAfter instead of addTab, then you have to specify the <after> parameter (categories, websites, upsell...).

例如，我编辑了您的教程代码:

I edited the code of your tutorial for example:

<reference name="product_tabs">
    <action method="addTabAfter">
        <name>custom</name>
        <block>inchoo_customlinkedproducts/adminhtml_catalog_product_edit_tab</block>
        <after>upsell</after>
    </action>
</reference>

我希望这对你足够灵活.

I hope this is fexible enough for you.
