Tamas,
You said your field had 6 sequence numbers on left and last two had year. But this string as I see it is: 2 + 6 + 2.

index on right(myField,2)+substr(myField,3,6) tag mySeq
* or you might be after this one:
index on right(myField,2)+left(myField,8) tag mySeq

Would you do this:

select top 10 rand(), myField from myCursor into cursor crsTemp order by 1
copy to mySample.txt type delimited
modi comm mySample.txt

Copy paste what you see + how they should be ordered.
