It seems that the behaviour o parameter expansion flag in Zsh differ by OSes. In Arch Linux, the leading spaces are exclude when it is sorting.

# Mac and Ubuntu
$ a=(' a1' 'a0' ' b1' 'b0')
$ echo ${(o)a}
 a1  b1 a0 b0

# Arch Linux
$ a=(' a1' 'a0' ' b1' 'b0')
$ echo ${(o)a}
a0  a1 b0  b1

Then it's a locale problem. Thanks for investigating!
