If you can't immediately update Moodle and the Cloze question plugin, and you're in a hurry, try enclosing the subquestions with div tags as follows:
<p>“Durantemi infancia, mi familia y yo (vivir)<div style="display: inline-block;">{1:SA:=vivíamos}</div> en la ciudad y mi mamá nunca nos (dejar) <div style="display: inline-block;">{:SA:=dejaba}</div> salir a jugar a la calle...
These tags are not needed with the latest versions of the plugin, but I think they won't hurt when you've made the updates.
