I think something like: 
$val = $default_val if $val eq '';

is easier to read and has the same effect as your code. 
$val ||= $default_val;

Does not have the same effect as your code. It will set the default value if $val is false but not necessarily the empty string. 
$default_val = "default";
$val = '0';
$val ||= $default_val;
print $val;

[download]
will print default even though $val is not and empty string;
