My brain is working slower than usual, sorry about the confusion.

After re-rereading the OP question, and properly testing your solution I
now get it.

Agreed, a slightly improved version, but still a lot of work:

find . -type d | while read dir; do 
  find $dir -maxdepth 1 -type f | wc -l | tr -d '\n'; print ":$dir"
done | sort -n

But nowhere near as efficient or elegant as the suggested zsh solution,
sorry about the noise and thank you for your patience :).
