Yes, you're right, I think.  You seem to be using a Python not linked with
cygwin1.dll, so it knows nothing about cygwin paths like /foo/bar/baz.
Your Python wants to be given a path to load its script from that looks
like c:/foo/bar/baz -- a standard windows path.  Cygwin finds your script
in /usr/local/bin, and passes that to Python, which Python doesn't
understand.  I don't know why cygwin does this in when it finds the path
in PATH, but not when you run a script by doing

cd /usr/local/bin
./test1.py

but that's what appears to do.  It's less suprising that this works:

d:/path/to/cygwin/usr/local/bin/test1.py

or

python `cygpath -w //usr/local/bin/test1.py`

Your other option is to get a python built under cygwin.  There are
probably binaries around now.
