Looking to get some insights on how others use the tool.

The Moz Grader is grading by exact keyword match only, right now it does not function to grade based upon a phrase match or broad match... that would be a pretty sweet function though : ).

Generally speaking though (with right on-site), if you're optimizing your page well for your main keyword phrase "entertainment public relation firms"... Google is going to rank you for other phrase match terms as well. This of course is dependent upon other on-site factors like, keyword density of the article/website, site architecture, inner-site and off site links, etc.... I would suggest you look a little deeper into your overall site architecture as well so you understand how to organize your site content best for indexing. Here's a great Moz White Board Friday (WBF) on this topic. http://moz.com/blog/whiteboard-friday-flat-site-architecture

The grading tool is used as a 10,000 foot view of the page.  It analyzes to the webpage to look for the proper usage of exact keyword phrases throughout the webpage.  It is not designed to analyze for synonyms or variations of keywords.

If you wanted to score a good grade for the variation you specified, then you would need to through that exact phrase in your Title, etc.  Keep in mind, though, the grading tool is not an indication of great SEO, just an indication that you have used keywords in the locations most highly correlated with positive results.
