Align Text Left Scripting

I’m new to scripting with After Effects and I’m having troubles doing the simplest thing. I got most of my program to work just fine, however, when I used the built-in text replace function it changes my text from left aligned to center aligned. I need to set my text layer to left align again after the text it changed.

Can anyone please help me? I know this is very basic, I just can’t find anything in the scripting guide that will help.

My last resort option is to set the anchor point of the text field but I would rather just set the alignment.

Here is the replace function:

replaceTextInLayer(app.project.item(99).layer(8), "Original", "New")

I just want to left align this text layer.

app.project.item(99).layer(8)

Thanks in advance for your help!
