You either need to define "blah" globally as you said, or define it in a 
tag that surrounds the context where you want to refer to it:

<span tal:define="blah tab/id">
  ...
    <div tal:condition="python:item.folder_type == blah">
       ...
    </div>
  ...
</span>

In either case, your python expression would simply be:
item.folder_type == blah
