For adding the tab use xml

 <adminhtml_catalog_product_action_attribute_edit>
        <reference name="attributes_tabs">
            <action method="addTab"><name>test</name><block>test/adminhtml_test_edit_tab_itemform</block></action>
        </reference>
</adminhtml_catalog_product_action_attribute_edit>
