Its a character set issue. IBO gets is data from IB/FB which sorts
according to the character set and collation defined there. Windows
has its own character-set/collation which often has a different sort
order. Hyphens are one of those characters than often trip the
difference.

eg: My Windows sorts the following as shown:
7777
7811
78-11
78-21
7999

The same listed sorted in a charset none database comes out as:
7777
78-11
78-21
7811
7999


You must assign code to the TIB_Connection.OnCustomCompareStr and
OnCustomCompareText functions. For example, if you dataset is
using a character of none (equivalent to ASCII) then you can
simply embed code that uses the VCL CompareStr and CompareText
functions (IBO uses the AnsiCompareStr and AnsiCompareText functions
by default).
