Just a guess :
.local/share/letsencrypt/lib/python2.6/site-packages/certbot_apache/constants.py
has a switch block
CLI_DEFAULTS_DEFAULT
     version_cmd=['apache2ctl', '-v'],
CLI_DEFAULTS_CENTOS
     version_cmd=['apachectl', '-v'],
CLI_DEFAULTS_GENTOO
     version_cmd=['/usr/sbin/apache2', '-v'],
etc.

It may be that certbot recognizes CentOS, but doesn't recognize SL and 
so uses the default. There's something in
.local/share/letsencrypt/lib/python2.6/site-packages/certbot/util.py
that seems to be looking for release versions but I don't fully 
understand it.
If you can add scientific linux to constants.py and get it to woek, 
maybe we can ask them to patch it upstream.
