I tried this, but it doesn't work either:

Created a wrapper script "schleuder-wrapper.sh" with following content:

#!/bin/sh
scl enable ruby193 /opt/rh/ruby193/root/usr/local/bin/schleuder listname at hostname

Then I changed the entry in /etc/aliases to this:

name: "|<PATH>/schleuder-wrapper.sh"

This is the error message in postfix log,
when sending mail to the alias name:

Command died with status 1: "<PATH>/schleuder-wrapper.sh". 
Command output: Unable to open /etc/scl/prefixes//opt/rh/ruby193/root/usr/local/bin/schleuder! 

Can you explain what happened here?

fyi and thanks for your support!
