ACPI weird behaviour

Hi, I've made a little script for myself (well not only for myself) for switching between states of bluetooth and wifi. weird thing is, when I run it from the command line, it works just fine. when I call it via acpi it cycles only two stages back and forth. can anyone please point out where I am going wrong?

my /etc/acpi/events/thinkpad.conf

event=ibm/hotkey HKEY 00000080 00001005
action=/usr/local/bin/rf

my script /usr/local/bin/rf

#!/bin/ksh

# or run this script as root. SUID flag is possibly dangerous, so be careful.

# to set suid flag run these two commands

#  sudo chmod a+s $(which rfkill)

wlaniface="wlan0"

list=$(rfkill list)

bluetoothsoft=$(echo "$list" | sed -n '2p' | awk '{ print $3 }')
bluetoothhard=$(echo "$list" | sed -n '3p' | awk '{ print $3 }')
wifisoft=$(echo "$list" | sed -n '5p' | awk '{ print $3 }')
wifihard=$(echo "$list" | sed -n '6p' | awk '{ print $3 }')

#notify-send "$bluetoothsoft $wifisoft"

if [ $bluetoothsoft = "no" ]; then
 bs=0
else bs=1
fi

if [ $bluetoothhard = "no" ]; then
 bh=0
else bh=1
fi

if [ $wifisoft = "no" ]; then
 ws=0
else ws=1
fi

if [ $wifihard = "no" ]; then
 wh=0
else wh=1
fi

if [ $wh -eq 1 -a $bh -eq 1 ]; then
 state=0
fi

if [ $ws -eq 1 -a $bs -eq 1 ]; then
 state=1
# both down
fi

if [ $ws -eq 1 -a $bs -eq 0 ]; then
 state=2
# wifi down, bt up
fi

if [ $ws -eq 0 -a $bs -eq 1 ]; then
 state=3
# wifi up, bt down
fi

if [ $ws -eq 0 -a $bs -eq 0 ]; then
 state=4
# both up
fi

case $state in
 0) #notify-send "RFKILL switch off";;
    ;;
 1) 
    rfkill unblock 0 
    rfkill block 1
    #notify-send "turning bt on"
    ;;
 2) 
    rfkill unblock 1 
    rfkill block 0 
    ifconfig $wlaniface up
    #notify-send "turning wifi on, turning bt off"
    ;;
 3) 
    rfkill unblock 0 
    rfkill unblock 1
    ifconfig $wlaniface up
    #notify-send "turning both on"
    ;;
 4) 
    rfkill block 0 
    rfkill block 1
    #notify-send "turning both off"
    ;;
esac

BTW: I used to use ordinary echo, but acpi didn't print out these messages, so I had to use the notify-send
