Well, there is also t3lib::int_from_ver() which helps a bit. But it 
cannot cope with trailing strings like "RC1".

Here's an alternative version:

function int_from_ver($verNumberStr)    {
  if (ereg('\d+)\.(\d+)\.(\d+)',$verNumberStr,$verParts)) {
   return 
intval(sprintf('%d%03d%03d',$verParts[1],$verParts[2],$verParts[3]));
  }
  return 0;
}

It simply ignores anything before or after the version itself.
