There is no chance to specify that the new column should be before/after
one column in an existing table.
You have to re-create your table.
possible way:

rename existing table to old_xyz
create table xyz as select <use the wanted sequence of column> from old_xyz
re-create indexes, synonyms, views, privileges on xyz.

Or another workaround:
rename existing table to old_xyz
create view xyz as select <use the wanted sequence of column> from old_xyz
re_create privileges on xyz.
When doing DDL (creating indexes for example) you always have to use old_xyz.
