Question about ADO OpenSchema method relating to Oracle

I am trying to read the foreign keys of our Oracle database with ADO's OpenSchema method using the adSchemaForeignKeys constant. I am retrieving the information but I am having a little bit of trouble interpreting what I get back. The Ordinal field that I get  is what I have a question about. I can't find this in any of the Oracle DBA tables. I assume that this must be something that ADO is generating. My question is how does ADO generate the Ordinal field value and what does it mean? An example of three records  from the OpenSchema method is as follows:

PK_TABLE_CATALOG            Null
PK_TABLE_SCHEMA             DA01
