Welcome to the Microsoft Q&A Platform. Thank you for reaching out & I hope you are doing well.
I was able to reproduce this.
It appears the sorting is considering the field as a String instead of a Integer value, hence this is happening.
I shall raise this internally and get it fixed.
However, it might take a while for the Product Team to fix this "cosmetic bug" and the change roll out across regions.
Cheers,
Kapil
