That's not valid nesting, hence the compilation error.

better to learn how to use ZPT :-)

Here's one solution:
...
  <td>
    <b tal:omit-tag="python:item.Flags !='B'"
       tal:content="item/desc"> 
         Description of the item
    </b>
  </td>
...

Here's another solution, using css classes:

.darker {font-weight: bold}

</style>
...
</head>
<body>
...

  <td>
    <span tal:class="python:item.Flags=='B' and 'darker' or nothing"
          tal:content="item/desc"> 
         Description of the item
    </span>
  </td>
...
</body>
