[SOLVED] Sort on multiple keys

Can you guys pls take a look at this.

I need to sort this list of numbers as follows:

2nd col first, then 1st col, then 3rd col, all in reverse (highest to lowest).

I'm doing this:

sort -k 2,2nr -k 1,1nr -k 3,3gr

but, as you see, the 3rd col does not get sorted properly.

Any idea about what's going on?

I'm highlighting in bold the two items not properly sorted:[FONT=Courier New]

Sorry... My mistake. I see the 1st col is not what I initially read.

It's all ok!

Thansk though.
