Magento Change Tab Order in Edit Product Section
===

I want to change order of tabs in edit product section.For example,categories and inventory tab must be swapped.Overriding `Mage_Adminhtml_Block_Catalog_Product_Edit_Tabs` block doesn't seem to work.

Config.xml

    <config>
    	<global>
    		<blocks>
    			<my_module>
    				<class>Company_Adminhtml_Block</class>
    			</my_module>
    			<adminhtml>
    				<rewrite>
    					<catalog_product_edit_tabs>Company_Adminhtml_Block_Catalog_Product_Edit_Tabs</catalog_product_edit_tabs>
    				</rewrite>
    			</adminhtml>
    		</blocks>
    	<global>
    </config>


I copied `Company_Adminhtml_Block_Catalog_Product_Edit_Tabs` into `local` folder and swapped the category and inventory `addTab` code.Any pointers?
