Question Sort Oddity

All,

I'm baffled by some sort behavior on SunOS 5.10 and looking for guidance.

Running the command:
Code:
sort -t'|' -k5,5 -k7,7 -k1,1 -k2,2 -k3,3 -k6,6 -k8,8 test

Against the file "test":
Code:
thirdA||||first||second|Data
thirdB||||first||second|
thirdC||||first||second|Data
thirdD||||first||second|Data

Yields:
Code:
thirdA||||first||second|Data
thirdC||||first||second|Data
thirdD||||first||second|Data
thirdB||||first||second|

Since the first (5) and second (7) sort keys are equal, I'm expecting the differentiating factor to be the third (1) and for the file to look as it did prior to the sort; however, because thirdB's last field (8) is blank, it appears at the bottom. If I put any content in this field it sorts as expected.

I get the same results whether my locale is "C" or "en_US.ISO8859-1." Can someone explain this behavior or how to achieve the sort I'm after?

Thanks much!
