Dropdown Down Menus Aren't Sorting With Their Cells

when I sort data columns that contain drop-down menus. My spreadsheet has several columns: "Patient name", "Room #", and "Phone #". Each cell within the "Phone #" column should have a drop-down validation list containing two possible entries: the room's designated telephone number, or NONE. Whenever I add a new patient to a room, these three columns need to be sorted alphabetically by patient name. But when I sort all three lists simultaneously, it looks great- but then I realize that the drop-down lists associated with each "Phone #" cell haven't sorted! They stay in their original location and don't sort with their cell. So the designated telephone numbers for each room are all screwed up.
