And that phenomenon is explained here: http://www.gnu.org/software/gawk/manual/gawk.html#POSIX-String-Comparison "6.3.2.3 String Comparison with POSIX Rules The POSIX standard says that string comparison is performed based on the locale's collating order. This is the order in which characters sort, as defined by the locale (for more discussion, see Locales). This order is usually very different from the results obtained when doing straight character-by-character comparison.34 Because this behavior differs considerably from existing practice, gawk only implements it when in POSIX mode (see Options)." -Dimitry
