Please help with more syntax! I turns out that I need an array as well, to retain the order of the source files. Something like the "<<WRONG" line here: 
my (%compdata, $comp, $file, @srcfiles);
for (@data) {
  my ($key, $value) = split /=/;
  for ($key) {
    /component/  && do { $comp = $value; last };
    /version/    && do { $compdata{$comp}{version} = $value; last };
    /sourcefile/ && do 
    { 
        $file = $value; 
        push  (@($compdata{$comp}{$srcfiles}), $value); # <<WRONG
        last 
    };
    /sourcesum/  && do { $compdata{$comp}{sources}{$file} = $value };
  }
}

For example, when the data is 
 component=HF
version=NULL
sourcefile=file10
sourcesum=checksum10
sourcefile=file2
sourcesum=checksum2
sourcefile=file3
sourcesum=checksum3

[download]
When using only the hash, the output is 
'sources' => {
       'file3' => 'checksum3',
       'file2' => 'checksum2',
       'file10' => 'checksum10'

but I need to be able to get the same order as the provided data (by using foreach @srcfiles { get hashvalue } (which is also syntax I don't know)) 
'sources' => {
       'file10' => 'checksum10'
       'file3' => 'checksum3',
       'file2' => 'checksum2',
