Wouldn't you want to use 'ls -lt' (sort by time) (or possibly with '-r' if you really want oldest first)? (I.e., does 'om' sort the glob passed to 'ls', which it will then reorder, or does zsh do something magic with the 'ls' command?)
yeah if you were typing this case yourself you would use -lt but i figured it was worth showing that extended globs can be combined.
This globbing functionality in zsh is separate from the ls command, so no ls magic here, but the ls builtin in zsh does have some useful extras in it all the same
