Use the source, Luke.  Having never actually done so, I suspect that the
answer to your question may be simply that OS detection was implemented
before service detection.

I just ran a few scans with the OS probe and Version

detection is being done before the Version  detection.
Why is this so?  Is it some performance issue or is it
using this information in some way.

Or is this just random and the 2 types (OS vs Version)
of probes can be sent one before the other or vice
