I don't understand this statement.  If code outside of moab is calling
iMesh_createTag then it should be checking for iBase_TAG_ALREADY_EXISTS.  If
code inside MOAB is calling tag_get_handle, it should *not* need to check
for MB_ALREADY_ALLOCATED, regardless of whether or not some other code
either inside of MOAB or outside already created the tag.

Any error code other than MB_SUCCESS returned from tag_get_handle indicates
that the existing tag did not have the expected type (unless you pass
MB_TAG_EXCL, in which case you are explicitly telling MOAB that it is an
error for the tag to already exist.)

Was there a specific error you encountered that your changes to ParallelComm
fixed?
