You're off by a digit, but that's understandable. We all are so used to calculators that I miss a digit often! October 1 was around 30,000. Actually 109630000. I bet yours is 109720067 - or about 90,000 higher than October 1.
90,000 cars were therefore ordered worldwide since October 1. That's about right.
BTW - lots of us have had experience with custom orders. What we're used to is that custom orders are given accurate time frames (with reason). Tesla said 2-3 weeks to many of us for a very long time. Most of October was listed as 2-3 weeks for many of our orders. Well, Tesla wuz wrong!
And Tesla really isn't custom ordered like most cars. For Model 3 you get trim type (3 of them), color (5 of them), wheels (not really hard to configure - but 2 of them), and that's it. Options are kept to a minimum to keep it like a Chinese buffet. Its not like ordering a BMW with a ton of options or packages and trim levels. And it's not like they are delivered in order of RN sequence anyway.
I ordered a month ago (Oct 11th). You could easily get a car before I do.
