Iterating over a list (coming from a script) is as usual:

<span tal:repeat="element container/list_making_script">
  <span tal:content="element/attribute">Value of some attribute of an 
element of a list</span>
</span>

Iterating over a dictionary's values is thus:

<span tal:repeat="value context/dictionary/values">
  <span tal:content="value">Value from a dictionary</span>
</span>

(Note that this is the usual Python method for getting the values of a 
dictionary. In Python, one would say dict.values() instead. You can also 
use dict.keys(), or with a little more work, dict.items() in the same 
manner.)

So put 'em together:

<span tal:repeat="dictionary container/list_making_script">
  <span tal:repeat="value dictionary/values">
    <span tal:content="value">Some value from a dictionary in a list</span>
  </span>
</span>
