For new version of iTerm

tell application "iTerm2"
  tell current session of current window
    set background color to {$(($R*65535/255)), $(($G*65535/255)), $(($B*65535/255)), 0}
  end tell
end tell

... I'm using this to simply set random dark colour for my terminals:

#!/bin/bash
set_term_bgcolor() {
  local R=$1
  local G=$2
  local B=$3
  /usr/bin/osascript <<EOF
tell application "iTerm2"
  tell current session of current window
    set background color to {$(($R*65535/255)), $(($G*65535/255)), $(($B*65535/255)), 0}
  end tell
end tell
EOF
}

set_term_bgcolor $(($RANDOM % 25)) $(($RANDOM % 25)) $(($RANDOM % 25))
