You could use the csound command line option `-L' with a named pipe.
The following example works with s7:
Csound orchestra test.orc:
print p1, p2, p3, p4, p5
csound -L score -odac -+rtaudio=null --orc test.orc
(define score (open-output-file "/path/to/score"))
(define* (csound-test (instr 1) (dur 1.0) (freq 440) (amp 0) (port score))
(format port "i ~D 0 ~F ~F ~F~%" instr dur freq amp)
(csound-test 1 1.5 1234 -6)
(csound-test :dur 3.2)
(csound-test :amp -3 :freq 660)
;; Remember to close the port.
