This is not that baroque once you grasp how the writer is approaching the sort. I looked at this quickly and knee-jerked that the logical expression is Wrong then I realized that it was in a sort block.

The writer is using short-circuiting to exit the block with -1 or 1 values; so that listtype sorts before listcode before funclist before every thing else.

I don't write that way. This seems to rely on luck as the block may yield "" which sort is not advertised to accept. I think it needs a catch-all  or ( $a cmp $b ).

Be well.
