<title>Product Description</title>
<block>catalog/product_view_description</block>
<template>catalog/product/view/mycustomtab.phtml</template>
</action>      
</block>

Answer 1

1) I think You should add custom tab to product view handle , or for specific product via admin Manage Product.

2) You can try native magento methods like this:

<block type="catalog/product_view_description" name="product.description" as="description" template="catalog/product/view/description.phtml">
   <action method="addToParentGroup"><group>detailed_info</group></action>
   <action method="setTitle" translate="value"><value>Description</value></action>
</block>

3) If You want to use Your method You should use reference instead of block, but again only for product

<reference name="product.info.tabs">
    <action method="addTab" translate="title" module="tag">
        <alias>product.tags</alias>
        <title>Product Tags</title>
        <block>tag/product_list</block>
        <template>tag/list.phtml</template>
    </action>
</reference>
