By default Zsh does not expand glob patterns in variables when using
parameter expansion. You can change this behavior using the GLOB_SUBST
option. Add the following line to the top of your script, and it should
work like you expect.

  setopt GLOB_SUBST

For more info check out GLOB_SUBST in `man zshoptions`
