Gawk: PROCINFO["sorted_in"] does not sort my numerical array values

Hi,

PROCINFO seems to be a great function but I don't manage to make it works.

input:
Code:
B,A,C
B
B,B

As an example, just want to count the occurence of each letter across the input and sort them by decreased order.

Wanted output:
Code:
B 4
A 1
C 1

When I use this command, the PROCINFO does not have any effect:
Code:
echo -e "B,A,C\nB\nB,B" | gawk '{a=split($0,b,","); for(i=1; i<=a; i++){count[b[i]]++}}END{PROCINFO["sorted_in"]="@_val_num_desc"; for(k in count){print k FS count[k]}}'

I get this output:
Code:
A 1
B 4
C 1

Could someone explain me what I am doing wrong?

Thanks !

irsend [options] DIRECTIVE REMOTE CODE [CODE...] DESCRIPTION
Asks the lircd daemon to send one or more CIR (Consumer Infra-Red) commands. This is intended for remote control of electronic devices such as TV boxes, HiFi sets, etc. DIRECTIVE can be: SEND_ONCE - send CODE [CODE ...] once SEND_START - start repeating CODE SEND_STOP - stop repeating CODE LIST - list configured remote items SET_TRANSMITTERS - set transmitters NUM [NUM ...] SIMULATE - simulate IR event REMOTE is the name of a remote, as described in the lircd configuration file. CODE is the name of a remote control key of REMOTE, as it appears in the lircd configuration file. NUM is the transmitter number of the hardware device. For the LIST DIRECTIVE, REMOTE and/or CODE can be empty: LIST "" "" - list all configured remote names LIST REMOTE "" - list all codes of REMOTE LIST REMOTE CODE - list only CODE of REMOTE The SIMULATE command only works if it has been explicitly enabled in lircd. -h --help display usage summary -v --version display version -d --device use given lircd socket [/var/run/lirc/lircd] -a --address=host[:port] connect to lircd at this address -# --count=n send command n times EXAMPLES
