I'm sorry you've had such a frustrating experience.
But the good news is that at least they acknowledge the autism, and the social communication needs. You should also know that it's not all or nothing. You can partially reject the IEP, accepting the parts that you agree with, and rejecting the finding that there is no need for OT services, and additionally requesting the ABA evaluation. Then the pragmatics/social skills interventions can start while the ABA eval is pending. Plus, you have in place the finding of eligibility. The team reconvenes after the additional eval is complete, and revises the IEP as indicated.
If they didn't reference your sensory rating scale at all, I would start by inquiring about the printed copies of evaluation reports from each specialist, which you have a right to. Then you can ask for clarification about the interpretation of your rating scale versus your daughter's or her teacher's. For future reference, you have a right to request evaluation documents at least two business days prior to the IEP meeting, which would allow you to catch any of these inconsistencies earlier. I presume the pre-eligibility meeting was supposed to address this right, by presenting you with the findings at least two days prior. You still want the papers in your hands, though.
As to the timeline for the new IEP: actually, districts have been cited by compliance officers for coming to the table with a pre-written IEP, as it violates parental due process (your right to have a say in development of the IEP). I'm surprised they get as long as 30 days to write it, though. In my state, the new IEP has to be issued within 3 school days, unless a summary of services goes home with the parent, in which you get 10 school days.
ETA: I just looked up your state, and see that you have a multi-part process, where there is an eligibility conference first, then they have 30 days for the IEP team, and another 10 days to issue the IEP. Although different parts of the website say 20 days for the same thing. I think they may be switching back and forth between calendar and school days.
Here's a timeline:
