OK, I think I'm finally getting to the bottom of this.
The below is from the realoem.com *TPMS* page which must be where my service guy was looking
for application, see illustration BMW

so it looks like for a 2009 there were at least three options - no dot, orange, or green. Now here's the funny thing - the 36136775937 part number isn't listed above! I think the other option that the dealer parts guy mentioned was gold? not sure? Aaaargh, I'm about to kick puppies! Damn you BMW for making something simple into something so difficult!
I'm going to go out on a limb and guess that I really do need to order the P/N 36136775937 and also that the most common BMW valve stem must be the 36111095375/36146792829 application which is the ones that Tire Rack will sell you if you order from them. So of course my car is speshul... figures. Do I roll the dice and order from Tischer? I think I do... 'cause I need new center caps too and Sterling BMW I think sells parts at a markup from list
