A name sort that crashes

sort_names should list customer names A–Z without caring about capital letters, keeping each name exactly as it was typed. Instead it stops with TypeError: '<' not supported between instances of 'builtin_function_or_method' and 'builtin_function_or_method'. Find the bug and fix it.
