Word will always resequence certain column names (basically, "Address" type
field names that it recognises, such as City, Firstname etc.) in the Edit
Recipients dialog. As far as I know there is no way to force Word to keep
your sequence except to avoid using those names. In many cases you could for
example put a "_" (underscore) at the beginning of the name, and Word will
/probably/ retain your sequence. If that doesn't work and Word sequences in
alphabetic order you would need to do something like put "01" at the
beginning of the column name you want o appear first, "02" at the beginning
of the next one, and so on.
