You can call page templates and pass them parameters (thus, you
do not need to add a script in between):

  <tal:div content="python: yourTemplate(yourVariable=Value1)" />
  ....
  <tal:div content="python: yourTemplate(yourVariable=Value2)" />

You can access the variable via "options" in your template

    <tal:div define="
      yourVariable yourVariable | options/yourVariable;
      "
    >
      ....
    </tal:div>
