Can jade Iteration have a Micro-Templating variable?

Am using jade as express.js view engin, and I use Micro-Templating ; here is a problem i came across here is the template

 script(id='form',type='text/html')
    select(id='select_category',name='product_category')
       option <%= option%>

to use the template

$(tmpl('form',{'option':'something'}))

now i have more than one option so this is what i did

i change the template

 script(id='form',type='text/html')
    select(id='select_category',name='product_category')
       each val,key in  <%= option%>
           option <%= val%>

using

 $(tmpl('form',{'option':[some arr]}))

this will cause a error says "Unexpected token < ";

so how can i do this?
