I think i have found a solution for this

Use the Universal Movie scraper set all the fields to TMDB, except for the ratings, select OMDBAPI
I tried this for a few movies and this was the result in the nfo file for Thor

xml:
  <ratings>

    <rating default="false" max="10" name="themoviedb">

      <value>6.7</value>

      <votes>14941</votes>

    </rating>

    <rating default="true" max="10" name="imdb">

      <value>7.0</value>

      <votes>723305</votes>

    </rating>

    <rating default="false" max="100" name="rottenTomatoes">

      <value>77.0</value>

      <votes>0</votes>

    </rating>

    <rating default="false" max="100" name="metascore">

      <value>57.0</value>

      <votes>0</votes>

    </rating>

  </ratings>

Check it out and let me know if it works for you.

I don't have the option to set omdb as a scraper for ratings. What version are you using? I either TMDB, IMDB, rotten tomatoes, or Metacritic...There are the "Also Get" options...but the only results i get are what has been set from the "Get Ratings from " Option

I'm using version 3.1.6
I've just had another look and maybe i should have been more clear, it's the Universal Movie Scraper from tmm.

Ok so that seems to have worked and gets me MOST of the way there, but theres a couple tags that it's not getting from rotten tomatoes that someone I think had previously mentioned 
the two tags listed below seem to not be available to scrape. It does however scrape a rotten tomatoes tag, but kodi doesn't recognize it upon loading the DB. So this gets me 80% of the way there, but not quite. Thank you for your help up to this point
