Lamont won his 90th cap against New Zealand, when replacing the injured Mark Bennett, and is set to start at Rugby Park on Saturday against Fiji.
But the 33-year-old - who has scored two tries in five GUINNESS PRO12 appearances for Warriors this term - claims he isn't counting down to the magic mark.
"I'm not here to count caps - I'm here to do whatever I can do for Scotland," Lamont told The Scotsman. "It [100 caps] would be a nice landmark.
"If I'm playing well and get there, I deserve it. If someone is playing better and I don't get there, so be it. It's whatever is best for Scotland. As you get older you appreciate every little bit you can get.
"I'll never declare myself unneeded. Someone will do it for me. Over my career I've gone from 'me first' to 'It's got to be Scotland first'. That's where I am.
"If I'm not used this weekend, that's fine. I won't be happy about it, but if that's what the boss thinks is best for Scotland then that is it. I'll take everything I can, but nothing is 100 per cent guaranteed."
