Are the initial files random, or are they already in some sorted order? If they are already random, just concatenate them together into one giant load file. Once loaded you can pull them out based on rownum so they will come out in the exact order they went into the table. Not truly random, but random as the initial files.

If the initial files are ordered, the above solution doesn't work. For a mySQL based table, you could do something like

SELECT * FROM BLA ORDER BY RAND()

although I'm not sure of exactly how random the results will be.
