title: How can we set priority in cucumber scenarios by using tags
body: <p>I am using protractor-cucumber framework, with protractor 5.2.2 and cucumber 3.2.1.
  I have given tags in my config. file as given below</p>
  
  <pre><code>tags: '@valid or @invalid or @empty'
  </code></pre>
  
  <p>By default it will execute the scenario that we written first. But i need to set priorities for scenarios from different feature file, so that higher priority will run first.Thanks in advance</p>
