Here's the prompt: Function for comparing keys (empty for default `sort-subr' predicate): And here's what sort-subr's docstring says about the behavior of the default predicate: If PREDICATE is nil, comparison is done with ‘<’ if the keys are numbers, with ‘compare-buffer-substrings’ if the keys are cons cells (the car and cdr of each cons cell are taken as start and end positions), and with ‘string<’ otherwise. That sounds like that should handle random's return value fine, so try entering an empty string at that prompt.
