sorting text file by date column

How to sort text file by date properly in sample below? The problem is that sort -k1,1 does not really work and neither can i use the dot notation such as sort -k1.6,1.9 -k1.4,1.4 -k1.1,1.2 because the form does not have a fixed length. I came up with this horror

awk '{split($1,a,".");print a[1],a[2],a[3],$2}' test.txt | sort -k3,3 -k2,2 -k1,1 | awk '{print  $1 "." $2 "." $3,$4}'

while it works, i don't like the complexity. Can this be simplified, ideally with just sort?
