it would just be a change in the dist tag appended to the release
number, and is not very important.

$ cat /etc/redhat-release 
Scientific Linux release 7.3 (Nitrogen)

$ rpm -qa --qf='%{RELEASE}\n'|grep -c 'el7'
1709

$ rpm -qa --qf='%{RELEASE}\n'|grep -c 'sl7'
25

I see that docker-1.12.6-16.sl7.x86_64.rpm is now available, maybe
you can try it.  However the corresponding container-selinux package
requires policycoreutils >= 2.5-11.  That version of policycoreutils is
not yet published in the SL updates tree, but should appear soon - it
is in fastbugs, so you would need to enable fastbugs to update it.
