        <block type="googlecheckout/link" name="checkout.cart.methods.googlecheckout.bottom" after="testproceed" as="testgoogle" template="googlecheckout/link.phtml"/>
    </reference>

        <block type="paypal/express_shortcut" name="checkout.cart.methods.paypal_express.bottom" as="testpaypal"  after="testgoogle"  template="paypal/express/shortcut.phtml">
