6.1.0

Description

Starting with [new TaggedValue('a', 5)], after a round trip through yaml, the number 5 becomes a string '5'.
The problem is clearly with the parser, because the dumped yml code seems correct.

How to reproduce

        $data = [5, new TaggedValue('a', 5)];
        $yaml = $this->dumper->dump($data, 2);
        $expected = <<<YAML
- 5
- !a 5

YAML;
        $this->assertSame($expected, $yaml);  // Pass.
        $this->assertSame($data, $this->parser->parse($yaml, Yaml::PARSE_CUSTOM_TAGS));  // Fail.

The standalone 5 survives the round-trip.
The tagged 5 becomes a string.

Possible Solution

Fix the parser. Not sure where exactly.
