I don't understand the value of this script. I realize I may just be missing the entire point so I will share my observations:
This script appears to simply perform the same function (at it's most basic level) as transmission-remote params | sort -k[x] where x= the field you wish to sort.
I tried passing a test to this script to see if it addressed what I thought was the key reason to want a script like this using:

ID     Done       Have  ETA           Up    Down  Ratio  Status       Name
 396   100%    4.16 GB  Done         0.0     0.0    0.0  Idle         Name10
 671   100%    4.74 GB  Done         0.0     0.0    0.0  Idle         Name01

The output carries forward the problem inherent in the sort command yielding:

ID     Done       Have  ETA           Up    Down  Ratio  Status       Name
 671   100%    4.74 GB  Done         0.0     0.0    0.0  Idle         Name01
