options are the parameter with the actual template was called with.  
Therefore

here/index_html has not options since it is not called as a method.
If I understand your problem correctly, you shoud do something like:

script:

pt = context.index_html
return pt(zerror="This is an error")

zpt:
<div tal:define"error options/zerror | nothing" >  
  <i tal:content="error"  tal:condition="error" />
  <div tal:content="structure here/body_content" />
</div>
