Script failing with "command not found: ^M"

When I try to run the following script in zsh, via the command /bin/zsh ~/.set_color_scheme.sh I get the following error:

command not found: ^M

The script has u+x permissions and it used to work on another machine that also had zsh. Any clues why?

Note: This question is related to this other question (where I am trying to adapt the script for tcsh)

#!/bin/zsh

Your shell script is in DOS/Windows text format (with CR+LF). Convert it to Unix format (e.g. use dos2unix).

This won’t work as you want though, as explained in the linked question. A new shell is executed, the variable it set, then the shell ends, taking the variable with it.

If you have a script that uses the same shell as the one you’re running (or has compatible syntax), then you can execute the script by using . or source. This way the script is run as if you typed it all in yourself, so all variables remain (and it will ignore the #! line).
