I think this is what you want:
$ sed 's/\([0-9]\.[0-9]\(\.[0-9]\)*\).*/\1/' <<.EOF   
 > 5.1
 > 5.1.1
 > 5.1.1-LINUX
 > 5.1.1-FC3
 > 5.1.1-RH73
 > 5.1.1_debug
 > 5.1.1_debug_O1G
 > 5.1.2
 > 5.1.2-LINUX
 > 5.1.2-FC3
 > 5.1.2-RH73
 > 5.1.2_debug
 > 5.1.2_debug_O1G
 > .EOF
5.1
5.1.1
5.1.1
5.1.1
5.1.1
5.1.1
5.1.1
5.1.2
5.1.2
5.1.2
5.1.2
5.1.2
5.1.2


So in your script:
release=$( echo $directory | sed 's/\([0-9]\.[0-9]\(\.[0-9]\)*\).*/\1/'
)
