a little trick i just discovered against area 1 boss whilst going for local ranking of 1st - before using an overdrive, lock-on to the maximum 8 targets then, while still holding [A] button, press overdrive button. all the overdrive shots will give you X8 points! EDIT: I CANT BE CERTAIN BUT IT MAY BE A 3 INSTEAD OF AN 8! oops.... still you should always be locking onto as many enemies as possible.

also, if you haven't already, i would suggest turning on the scoring display. i believe its in
'pause menu/ options /controls /show scoring ON-off'.

i found it it helped......

Try to memorise where and when enemies spawn and when to use your Overdrive effectively. The key to getting this is to try and lock on to as many targets at once for a combo bonus. Network Openings and boss cores don't count. Power-ups count when there are other baddies in the area. Also, don't focus purely on the boss' core when you reach it, try to get combo bonuses from shooting it's shell and projectiles.

Earn 150,000 or more points in Areas 1, 2, 3, and 4 and 300,000 or more points in Area 5 to reach the top of the local leaderboard. You can do the Areas in any order you please.

Durring the game you will get 2 kinds of enemy flows:
Heavy flow - Lots of enemies on the screen. Rockets Everywhere and missiles coming at you. When this happens try to rapid fire and get about 2-3 missiles/enemies per shot. There are enough enemies that this will gain you big points during the game.

Lighter flow - A few enemies on the screen that delay their attacks. Can result in a heavy flow if you don't take care of things fast enough. You may feel like you should rapid fire to take care of all the enemies fast enough (like when the large carrier ship things come into play) but concentrating your fire on one single enemy and maxing out your shot actually will deal with things quicker AND give you a HUGE point boost. Certain enemies give 200 points per kill and take about 8 shots to drop. If you drop them with one maxed out shot thats 200x8 = 1600 points per kill. Try to target the little guys first though because they tend to leave the screen sooner but they still give a reasonable amount of points.

Each boss battle can give anywhere between 50,000 - 20,000 points from the battle and each boss gives about 10,000 points. I can safely say that if you have about 130,000 pts going into each boss of stage 1-4 you should be perfectly fine.
