Queries skipped from the script

I faced one this problem in our production enviornment, same script run without any errors in other 3 test enviornments, but in the production recevied no ERROR message, but the effect of the queries not implemented in the tables.queries are on different lines in the script.

SQL> CREATE INDEX avg_pk ON avgor (id) TABLESPACE v_data_idx
SQL> ALTER TABLE ve.avgor DROP CONSTRAINT avg_pk
SQL> ALTER TABLE ve.avgor ADD CONSTRAINT avg_pk PRIMARY KEY (id)
SQL> ALTER TABLE ve.fry_avgor_dok ADD rat_sek_info CLOB
SQL> COMMENT ON COLUMN ve.fry_avgor_dok.rat_sek_info IS 'abc'
