If you want the name of the table along with the trigger name:

select tbl.name as TABLE_NAME, trg.name as TRIGGER_NAME

from sysobjects trg

inner join syscomments sc on sc.id = trg.id

inner join sysobjects tbl on tbl.id = trg.parent_obj

where trg.xtype = 'TR' and sc.text like '%[^A-Z0-9_]sales[^A-Z0-9_]%'
