How to Sort Floating Numbers Using the Sort Command?

Hi to all.

I'm trying to sort this with the Unix command sort.

Code:

user1:12345678:3.5:2.5:8:1:2:3
user2:12345679:4.5:3.5:8:1:3:2
user3:12345687:5.5:2.5:6:1:3:2
user4:12345670:5.5:2.5:5:3:2:1
user5:12345671:2.5:5.5:7:2:3:1

I need to get this:

Code:

user3:12345687:5.5:2.5:6:1:3:2
user4:12345670:5.5:2.5:5:3:2:1
user2:12345679:4.5:3.5:8:1:3:2
user1:12345678:3.5:2.5:8:1:2:3
user5:12345671:2.5:5.5:7:2:3:1

I want to sort it at first by the third row, at second by the fourth row and at least by the fifth row (using ":" as separator). To do it I'm trying to use this (but it doesn't works):

Code:

cat file_contains_example | sort -nr -t":" -k3 -k4 -k5

What can't I do to solve this problem? (I prefer to use sort)

Thank's for read.
