Description

Add condition type to fix parsing order. This is exactly the same as ExpressionType, shouldn't be a huge impact at all.

this probably fixes other issues too.

Looks good, I'd like to make sure this isn't going to (somehow) break a bunch of scripts by changing the parsing orders.

2.8 betas will find out, I didn't find any from the tests, but it gets the proper conditions to work, so that's a plus.

Conflicts need fixing.

Implementation is fine. The idea of condition priorities exists in #6246 which may end up getting merged for 2.10 (meaning this PR may only need to set priorities for something like CondCompare)

When I created this pull request, I wanna add that this fix actually turned out surprisingly well, it fixed so many issues, and it's very simple in the fact that it's just modifying the list order like Expressions with ExpressionType.

Oh yeah I think the idea is good. I'm fine with merging this.
