Instead of patchelf I made it work using a script that sets
LD_LIBRARY_PATH and then calls out to the scl python:

$ ls -l overrides/bin/
lrwxrwxrwx. 1 cloud-user cloud-user   9 30 sep 11.04 python -> python2.7
lrwxrwxrwx. 1 cloud-user cloud-user   9 30 sep 11.04 python2 ->
python2.7
-rwxrwxr-x. 1 cloud-user cloud-user 115 30 sep 11.17 python2.7

with overrides/bin/python2.7:
 #!/bin/sh
 export LD_LIBRARY_PATH=/opt/rh/python27/root/usr/lib64
 exec /opt/rh/python27/root/usr/bin/python2.7 "$@"

and overrides/ostree-build-yocto:
 #!/bin/sh
 export PATH=/data/gnome-continuous/overrides/bin:$PATH
 scl enable git19 "/data/gnome/root/lib64/gnome-continuous/ostree-build-yocto $*"

(Where /data/gnome-continuous is where i put the build root)

This seems to have worked so far, and I expect it to work all the way.
