You are very likely using a different copy of the Singular interface.
You should modify the file
SAGE_ROOT/devel/sage/sage/interfaces/singular.py
and change the line (1145) that creates the singular interface to
singular = Singular(logfile="/tmp/logfile")
Then do
sage -br
to have the changed version of singular.py copied over so it gets used by Sage.
