On all platforms, the scene manager window feels extremely dated. You should be able to drag/drop any scene to rearrange it. At the very minimum, you should be able to select multiple scenes and batch move them up/down in the order.

+++ EDIT +++
I just saw you’re on Mac, so the above won’t help you.
This is the latest version of Curic Scene Manager and it supports macOS.
Use the reorder position feature if you want to reorder the scenes.
@voquochai is version 1.1 going to be available via extensions warehouse? Presumably with a trial + fixed price license?
I’m pleased to see 1.1 is for Mac too, but would like to try before buy.
Curic Scene Manager is free, you can enter any price in the Name a fair price field.
Hi @voquochai, I tried to find the curic version 1.1 via extensiona warehouse, but I can find just the 1 version. Do you know please where I can get the latest version?
