For static text (text that doesn't change, like the world "score") just make that text into a sprite and display it at the desired location. (The down side is if you get so lucky as to need a translation of your game to other languages, you'll have to make each of these new graphics. You should be so lucky, right?)
For the dynamic text (text that changes, like the numeric score itself) it is a lot more work. I suppose you could create a sprite with the digits 0-9 and/or the letters of the alphabet. You'd have to deconstruct every number and switch the animation frames.
IMO it would be easier to use webfonts
for the dynamic text. Look and see if you find one that coordinates with your static text. (Here's a tutorial on using webfonts in C2
Note: I'm assuming you are using Construct 2. I don't know enough about classic to comment on it.
