How to order statistical data (spatial panel)

Hello all,

I will to perform a spatial panel data, I have statistical data of 2000+
territories in 5 years ordered as typical simple panel data (Each
territoriy has a unique geocode).

In the other hand I have a shapefile with those 2000+ territories, but,
when I've opened the dbf file, the order of units seems to have not order
criteria. These ones have geocode too (same than statistical).

The question is, how should I order my data to garantee a right matching
between statistical and geographical data?
