If ES6 I do this:

versions.sort((v1, v2) => {
  let [, major1, minor1, revision1 = 0] = v1.match(/([0-9]+)\.([0-9]+)(?:\.([0-9]+))?/);
  let [, major2, minor2, revision2 = 0] = v2.match(/([0-9]+)\.([0-9]+)(?:\.([0-9]+))?/);
  if (major1 != major2) return parseInt(major1) - parseInt(major2);
  if (minor1 != minor2) return parseInt(minor1) - parseInt(major2);
  return parseInt(revision1) - parseInt(revision2);
});
