when u do
if (1 < a)
so it checks if 1is less then ascii value of 'a' right ?

Yes, it would appear so. I don't see why you couldn't take 30 seconds to test it yourself as I just had to though.

tested, but it seems that it's not working like that
if (102 < a)
a ascii value is 97, so how 102 can be less then a ? the condition is true but it's not working like i thought ..
do u know ?

It treats 1, 0, and 2 as alphabetic characters and then compares their ASCII values with the ASCII value of 'a'. So it's comparing 49 (the ASCII value of '1') with 97 first of all, which means that '102' is smaller than 'a', just as 'angel' would be smaller than 'b'.

If you want to numerically compare 102 with the ASCII value of 'a' just use if (102 < $asc(a)).

so each comparison is first converted to ascii first? even when they both numbers ? i mean that if (1 < 2) will make it if (49 < 50) ?

No. Only when one of the operands is not a number.

No, only when mIRC finds itself running mathematical comparisons where one or more of the comparitive elements is non-numeric. (a < b) is meaningless in mathematical terms, but mIRC gets clever and compares the ASCII values. Because ($asc(a) < $asc(b)) is true, it can detect that "a" comes before "b" which is an "added feature" of the if-else comparison function in mIRC.

But, as we have seen in this thread, it can lead to complications where the other element is actually a number value.. because the other one is still non-numeric, it carries on converting both elements to their first ascii value. it's confusing, but does work as it's supposed to.

NOTE: only the first character in each element will count, because only one comparison can be made, and hence only one ASCII value taken into consideration. Remember, $asc(a) == $asc(ab).

ok thx

That's not true, if the first two ascii values are the same, the next two are compared, then the third, etc:
$iif(ab > aa,$true,$false) = $true

If two strings aren't of equal length, but the start of the longest is the same as the shortest, the longer string will be 'larger':
$iif(aa > a,$true,$false) = $true

Ofcourse, if you use $asc() yourself only the first character counts, because $asc only returns a numerical value for the first character and then the comparison is made:
$iif($asc(aa) > $asc(a),$true,$false)
is first converted to
$iif(97 > 97,$true,$false)
and then the comparison is made, resulting in $false

I stand corrected.
This must be an extension of the aforementioned feature, as in alphabetical terms, ab is indeed greater than aa. Eg. take a look at your Excel spreadsheets and scroll down. The columns go

A B C D E F G H I J K L M N O PQ R S T U V W X Y Z AA AB AC AD AE etc..

So mIRC's alphabetical comparison system is even more complex than I thought.
