I was able to sort a hash table by asigning numbers to the items in it. Depends on how do you want to sort I guess.
var %i = 1
while (%i <= $hget(helpreqs,0).item ) {
hadd -s helpreqs %i $hfind(helpreqs,(%i + 1)).data
hdel -s helpreqs (%i + 1)
inc %i
}
I belive you can parse the item or data into another variable and then sort it.
