Localize the package global first, and then call the lvalue sub: 
package Foo;
our $level = 1;
sub level :lvalue {$Foo::level}

package main;
print $Foo::level;
{
    local $Foo::level; # scalar localized...
    Foo->level = 2;    # ...works on localized scalar
    print $Foo::level;
}
print $Foo::level;
__END__

I read local Foo->level = 2 as trying to localize an expression (the lvalue sub itself?), and not the package global this sub operates on.

A quick look with Scalar::Util::refaddr tells me after the local() call I am indeed dealing with the same address still.
Hmm? $Foo::level is no reference - calling Scalar::Util::refaddr on it yields undef.
