Because of the with tag, you are inside the namespace of your newly created 
ZClass instance. _['MyFirstOptionList'] (or just plain MyFirstOptionList) 
will retrieve the MyFirstOptionList of that instance, which is empty.

You can copy the value using a let tag:

  <dtml-let def1=MyFirstOptionList def2=MySecondOptionList
   <dtml-with "MyTestZClass.createInObjectManager(REQUEST['id'], REQUEST)">
     <dtml-call "REQUEST.set('MyFirstOptionList', def1)">
     <dtml-call "REQUEST.set('MySecondOptionList', def2)">
     <dtml-call "propertysheets.Basic.manage_editProperties(REQUEST)">
   </dtml-with>
  <dtml-let>
