Control T will use your default Photoshop interpolation technique.
You can go to Image>Imagesize and at the bottom is nearest neighbor.
But if your re-sizing like what you have above it might be better to stick with BiCubic Sharper/Bicubic
Like the drawing im doing at the moment is 320x 240 but in game I double the size so when I scale it I use the nearest neighbor cause it will translate it up with out messing with the pixels.
I find that pixel art is more time consuming then higher res stuff, Though I feel both are pretty different.
As for the scripting stuff I have very little knowledge of coding/scripting and I haven't had any problems doing anything I wanted to do yet.
Good Luck.
