Sorting strangeness

[Paul Dupuis]

Okay, here is a Monday morning puzzler for folks:

Take the following text:

Chinese 中文
Georgian ქართული
Arabic عربى
Greek Ελληνικά
Russian русский
Norwegian Norsk

"sort lines of <original text> ascending international" produces exactly 
what is expected:

Arabic عربى
Chinese 中文
Georgian ქართული
Greek Ελληνικά
Norwegian Norsk
Russian русский

However, "sort lines of <original text> ascending text" produces:

Arabic عربى
Chinese 中文
Georgian ქართული
Greek Ελληνικά
Russian русский
Norwegian Norsk

Now, WHY should Russian appear BEFORE Norwegian with R before N in 
treating it as a straight ASCII sort ("text")???

Try it yourself in LC9.0.5rc1. Is this a BUG? or should unpredictable 
results be expected if using a default (as "text" is the default) sort 
of text in LC9.0.5?
