Ah, I had meant to suggest using --debug without -c.

When all keys compare equal, 'sort' falls back on a last-resort comparison of
the entire line to break ties, and it's finding that your lines are out of
order. You don't want 'sort' to do that, so you should specify the -s (--stable)
option. -s is a GNU extension.
