It occurs to me that another common usage of numeric file descriptors is when constructing the bit vectors for select (the RBITS,WBITS,EBITS,TIMEOUT version, not the FILEHANDLE one). You often see something like vec($rin,fileno(STDIN),1) = 1;, where you wouldn't need the fileno() if you already had a numeric file descriptor.
