I think your first example is backwards. Try 
foreach my $sourceLine ( @SourceData )
{
    if ( $sourceLine =~ /\b$functionName\b/ )
    {
        $counter++;
    }
}

Note that \b matches a "word boundary", which prevents matching on non-function names embedded in other "words" (including other function names). But it doesn't handle the problem where function names are mentioned in comments.
