Unfortunately, there is no built-in option for additional sorting in the month view, but you can apply sort by workaround - the idea is to add some seconds to the event start dates(based on custom logic) - so their actual date will stay the same, but their sort position will be changed based on the seconds date part.
Here is a simplified example(click on an event to add 1 second to its date, so it will change its sort order): https://snippet.dhtmlx.com/etwf0sd4
Technically you can use the onEventLoading event, and based on some custom sort property, set the event’s seconds part, so it will be sorted higher or lower
