title: NUnit Command line Switch /include: execution order
body: <p>I run nunit-console using the following command line:</p>
  
  <pre><code>nunit-console-x86.exe IntegrationTests.dll /include:InstallerTests,SanityTests,DebuggingTests /xml=IntegrationTestResults.xml /nologo /labels /timeout:960000
  </code></pre>
  
  <p>My issue is that the test runs in alphabetic order.  Is there any way to force NUnit to run the tests based on category order we mention in command line <code>/include</code> switch? I would like to run Installer tests first then Sanity and finally Debugging tests.</p>
  
  <p>One partial solution is to run individual categories separately but I want the test results in single XML file so that it is easy to manipulate results.</p>
