orderByPositionfunction

The choices in the order they run across the map, west to east.

Handles numbered by the option's place in a shuffled list read 3 2 4 1 from left to right, and the number keys pointed at nothing you could see. Numbering by position makes the handles a row to read and makes 1 mean the leftmost one.

It gives nothing away. Where a place sits is the entire question being asked, so ordering the choices by it tells the player only what the map already shows them. Ties break north to south, and anything with no centre keeps its order at the end rather than disappearing. centreOf says where an option is: (option) => region.centroid.
