Use of (#b)(#s) and $match needs extendedglob, which isn't enabled for "zsh -f".

BTW, the for-loop isn't needed, this is a one-liner except for the setopt:

#!/usr/bin/env zsh -f
setopt extendedglob
print -r -- ${${(L)@}//(#b)((#s)|[[:space:]])([[:alpha:]])/$match[1]${(U)match[2]}}

In the current development version, you can enable extendedglob for a
single parameter substitution with the (*) flag:

#!/usr/bin/env zsh -f
print -r -- ${(*)${(L)@}//(#b)((#s)|[[:space:]])([[:alpha:]])/$match[1]${(U)match[2]}}
