title: EMF sorting options with resource save api
body: <p>Our resource entities are getting sorted using Ascii values which produces an ordering that is inconsistent with human logic while doing an resource save.
  using resource.save().</p>
  
  <p>For eg: text1, text2, text 10 gets sorted as text1, text10 , text 2</p>
  
  <p>We expect it to be sorted as text1, text2, text10.</p>
  
  <p>Is there any way to get the entries sorted while we do a resource save,</p>
  
  <p>or is there any other way to approach it ?</p>
