This is actually much easier than you might expect - Essentially you are looking at merging two hashes with the key-values of %runset having precedence of those in %description. This can be done as follows:

delete $runset{$_} for ( grep { !/^[A-Z]+$/ } keys %runset );

%merged_hash = ( %description, %runset );

This code will delete the non-uppercase key-value pairs in the %runset and then merge the two hashes - Any values in %description with an identical key-name in %runset will be replaced with the values in the latter (based on left-to-right execution).
