I have an array of place objects, each with a name (unique) and number (non-unique). Is there a simple way to use sort_by to first sort by number and then (within each number) by name?

I know I can write a custom block for sort, but if this is possible, it'd be even easier!

Not sure if this is what you mean by "custom block" but it seems pretty simple to me:

places.sort_by { |place| [place.number, place.name] }
