Actually, the connect() scan could have problems in telling the difference between filtered and closed ports because when ICMP DU/PU is received then connect() returns ECONNREFUSED (just like when RST is received).
That may be platform dependent, certainly on linux protocol unreachable etc. are handled fine by connect() and have their own errnos (which nmap uses correctly).
