No, on the PS2 version if you saved at Cherry Poppers, you are prevented from getting 100%. That was the biggest bug on the game but it got fixed in the PC version.
San Andreas also had a lot of major bugs more than those in VCS and Vice City. Let me name a few, the Madd Dogg Safehouse glitch where if you save there, then you can't play basketball again. That was only a minor glitch since basketball was only for fun and weight loss. The most major glitch in the game was during the mission Madd Dogg where I heard he jumps off the ledge of the building before the first cutscene ends or something like that and that prevents you from completing the storyline and getting 100%. Vice City Stories was only full of minor glitches.
But, I'm going off-topic, anyway. I wouldn't be surprised if there are a few minor bugs like in Vice City Stories or major bugs (which I doubt a little) from Vice City or San Andreas in GTA IV.
