I modified the original script. Here's my script ...

set deskPath to (path to desktop folder) as text
set filePath to (deskPath & "x0000y.png") as text -- this file does NOT exist
tell application "Finder"
set fileExists to (exists filePath) as text
end tell
display dialog fileExists & return & filePath

try
filePath as alias
on error errText number errNr
"Error = " & errNr & return & errText
display dialog the result
end try

It is clear from the behavior of this script that the Finder has a serious bug.

No, it's clear that the script has a serious bug. It's passing the exists command a string instead of a reference.

Experiment with line 2 by increasing the number of zeros in the file name.

Strings behave this way:
"0" ≠ "00" ≠ "000" ≠ "0000" ≠ "00000"

Integers behave this way:
0 = 00 = 000 = 0000 = 00000

The Finder is behaving as if a sub-string of zeros is equivalent to zero,
which is erroneous integer behavior, not correct string behavior.

In my script, above, the Finder incorrectly thinks that:
"x0y" = "x00y" = "x000y" = "x0000y" = "x00000y"

Perhaps I should post this message as a bug report,

The Finder's exists command takes a reference to an object, not a string. You're passing a string, so whatever you get is irrelevant.
