Updates:

For some reason module load does work in the command line environment, though lmod can't find singularity.

[tanlin2013@scopion ~]$ module load singularity
Lmod has detected the following error: The following module(s) are unknown: "singularity"

Please check the spelling or version number. Also try "module spider ..."
It is also possible your cache file is out-of-date; it may help to try:
  $ module --ignore_cache load "singularity"

Also make sure that all modulefiles written in TCL start with the string #%Module
