Thanks David. I got the lists merged with the method you proposed, it
is actually something I do all the time with rhinoscript, just had not
tried the sorting in GH. Not exactly the result I was expected, but
now I understand why it is doing that. I figure I can do this in a
few other ways. Thanks for the tip!
