It looks like its of data type 'character' in the documentation at
http://mapserver.gis.umn.edu/doc40/perlmapscript-reference.html and at
http://mapserver.gis.umn.edu/doc44/swigmapscript-reference.html
Is the shapeObj->{values} in Perl not the same as the one in PHP?
Thanks,
Drew.

There is a shapeObj 'values' attribute in documentation at
http://mapserver.gis.umn.edu/doc44/phpmapscript-class-guide.html#ShapeObj

No ''values' attribute of a shapeObj is exposed in the SWIG Mapscript API.
Just numvalues and the getValue method.
