It’s very important to realise that notes are not sorted in projects on creation date but on assigned date, the date you assign to the note, you can quickly (re)assign notes to today (using cmd-return or by typing \today), yesterday (by typing \yesterday), etc and it will adjust the sorting accordingly.
Similarly, you can also after the fact link a note to a calendar date (by clicking the calendar icon next to the title) and have the note be sorted correctly.
Finally, undated notes and notes that have the same day assigned can be rearranged using drag-and-drop, or using the cmd-control-up/down arrow.
