You can always make use of .qpj files to force a specific EPSG code. The 
.prj file normally does not have EPSG codes inside (especially if they 
are from the Arcgis world), therefore the .qpj file was invented.
QGIS always creates .qpj files, so when you have set the CRS once 
correct, you can copy that semi-automated to any shapefile you get from 
outside.

By the way, the EPSG database states for EPSG:3067:

"Remarks:
Identical to ETRS89 / UTM zone 35N (code 25835) except for area of use. 
See ETRS89 / TM35FIN(N,E) (code 5048) for more usually used alternative 
with axis order reversed. "

And for EPSG:5048:

"Remarks:
Identical to ETRS89 / UTM zone 35N (N,E) (code 3047) except for area of 
use. Used in preference to ETRS89 / TM35FIN(E,N) (CRS code 3067) in 
which coordinate axes are in order easting-northing.

So the axis sorting is different, but that is not part of the proj 
definition.
