As it is the names that are given to screenshots in Mac OSX are not accurately named to be sorted alphabetical (and then numerical).

In the names below you'll see that a screen shot taken at 3PM is ordered before the picture taken at 12PM.

For it to be ordered correctly either 24hr military time needs to be used or the time needs to be 2 digits. IE "3.05.19" needs to be renamed to "03.05.19".

Is there a way to do this?

See my answer for a way to change the complete name sequentially. As far as I know, there's no other way (i.e. through the keyboard shortcuts or other than screencapture). Let me know if it doesn't work for you or so, I'll happily reopen and we'll figure things out. – slhck Oct 10 '12 at 20:28
Hi slhck - Thanks for the link but the solutions there don't answer my question. I'd like to keep the name the same but add either a "0" before the time or use military time. Well now that I think about it military time won't work. – 1.21 gigawatts Oct 11 '12 at 4:10

Screenshots use the Medium time format you specify in System Preferences » Language & Text » Times (with colons replaced by periods as they're invalid in file names). Click Customize… and enter a sane value there, and you're good.

FWIW, the US 12 hour clock format will never properly sort, even if you add the leading zero. 12.30 AM is an hour earlier than [0]1.30 AM... It's simply a stupid format. – Daniel Beck Oct 11 '12 at 6:37
