"Schedule For" sort order

[KevinT]

I use a single account to create scheduled meetings for all users. 

My other users are generic Room 01, Room 02, etc. 

When I click the dropdown for "Schedule For" the sorting of the "users" is all out of order, even though the users  were created and added in order. 

What I see is - 

Myself

Room 05

Room 02

Room 03

Room 04

Room 01

While currently this does not cause an issue, I can see where it will become an issue in the future. Is there a method to sort these appropriately?
