Put a print before the 'next if m/$finds_re/;' line, for a test run, ,and you'll see which lines match the regex and which don't.

Are you anticipating the patterns to match to change? The definition of quotemeta is:

quotemeta EXPR
quotemeta

Returns the value of EXPR with all non-"word" characters
back-slashed.  (That is, all characters not matching
"/[A-Za-z_0-9]/" will be preceded by a backslash in the
returned string, regardless of any locale settings.)  This 
is the internal function implementing the "\Q" escape in 
double-quoted strings.

Since your patterns are numeric, quotemeta is a no-op. If you expect the patterns to change, anticipation might be a virrtue, but otherwise it might simply be an unnecessary complication.
