bug#72159: Numeric sorting does not work with 100.000 values

[Martin MOKREJŠ]

Hi,
  I think I found a bug in sort from coreutils-9.5 on Gentoo Linux:

$ LANG=C sort -k 1 -k 3,3n -r somefile.tsv | head

The line 8 with value 100.000 should appear one line earlier, on line 7 (the 
value 100.000 should precede 98.000). I want to sort by first column and then 
numerically the float values in column 3, highest to lowest. It works for float 
values below 100.

Thank you,
Martin
