I haven't seen an awk solution yet, so here's one.  The strategy is
to generate a line which has the last field duplicated in front and
uses a different field separator.  I selected the "plus" sign.  There
needs to be some character which is not found in the data file.

#! /bin/sh
# 
awk '{print $NF "+" $0}' | sort -n -t+ +0 -1 ,t1 | awk -F+ '{ print $2}'
